Craftsman Chainsaw 917.353710 Tune-Up Tips (5 Pro Tricks)

1. The Fuel Factor: Optimizing Your Fuel Mix

The lifeblood of any two-stroke engine, like the one powering your Craftsman chainsaw, is the fuel mixture. Getting this wrong can lead to a host of problems, from poor performance and difficult starting to severe engine damage. I’ve seen firsthand the consequences of using the wrong fuel mix – scored pistons, seized engines, and a whole lot of frustration.

Understanding the Importance of Fuel-Oil Ratio

The fuel-oil ratio is critical. This refers to the proportion of gasoline to two-stroke oil in your fuel mixture. The manufacturer’s recommendation for the Craftsman 917.353710 is typically a 40:1 ratio. This means 40 parts gasoline to 1 part two-stroke oil. Using a ratio with too little oil leads to insufficient lubrication, causing excessive wear and tear on the engine’s internal components. Conversely, too much oil can cause excessive smoke, carbon buildup, and reduced performance.

Pro Tip: Use High-Quality Two-Stroke Oil

Don’t skimp on the oil. I learned this the hard way after using a cheap, generic two-stroke oil. The engine ran poorly, and I noticed excessive carbon buildup. Since then, I’ve always used a high-quality, synthetic two-stroke oil specifically designed for air-cooled engines. Synthetic oils provide superior lubrication, burn cleaner, and help prevent carbon deposits. Look for oils that meet or exceed JASO FD or ISO-L-EGD standards. These standards indicate a higher level of performance and protection.

Mixing Fuel Properly

Mixing fuel properly is just as important as using the correct ratio and high-quality oil. Here’s my step-by-step method:

1. Use a Clean Fuel Can: Always use a clean, dedicated fuel can for mixing fuel. Residue from old fuel or other contaminants can negatively affect the fuel mixture and engine performance. I label my fuel cans clearly to avoid confusion.
2. Add Oil First: Pour the correct amount of two-stroke oil into the fuel can first. This helps ensure that the oil mixes thoroughly with the gasoline. For a 40:1 ratio, you’ll need 3.2 ounces of oil per gallon of gasoline. I use a graduated measuring container specifically for two-stroke oil to ensure accurate measurements.
3. Add Gasoline: Slowly add the gasoline to the fuel can. Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline that has been sitting for extended periods, as it can degrade and lose its volatility.
4. Mix Thoroughly: Secure the fuel can cap and shake the can vigorously for at least 30 seconds to ensure that the oil and gasoline are thoroughly mixed.
5. Label and Date: Label the fuel can with the date and the fuel-oil ratio. This helps you keep track of the fuel’s age and ensures that you’re using the correct mixture.

Case Study: The Importance of Fresh Fuel

I once worked on a project where we were felling trees for a small cabin build. One of the crew members was having trouble starting his chainsaw. After checking the usual suspects (spark plug, air filter), I discovered that he was using gasoline that had been sitting in a can for over six months. Gasoline degrades over time, especially when exposed to air and sunlight. We drained the old fuel, mixed a fresh batch, and the chainsaw started right up. This experience reinforced the importance of using fresh fuel and storing it properly.

Strategic Advantage: Fuel Stabilizer

If you’re not going to use the fuel within a month, consider adding a fuel stabilizer. Fuel stabilizers help prevent gasoline from degrading and can extend its shelf life. Follow the manufacturer’s instructions for the correct dosage. I use a fuel stabilizer in all my two-stroke equipment, especially during the off-season.

Measurements and Specifications:

• Fuel-Oil Ratio: 40:1 (3.2 ounces of two-stroke oil per gallon of gasoline)
• Gasoline: Unleaded, 87 octane or higher
• Two-Stroke Oil: High-quality, synthetic, JASO FD or ISO-L-EGD compliant
• Fuel Stabilizer: Follow manufacturer’s instructions

2. Breathe Easy: Cleaning or Replacing the Air Filter

A clean air filter is essential for proper engine performance. A clogged air filter restricts airflow, causing the engine to run rich (too much fuel, not enough air). This can lead to reduced power, increased fuel consumption, and carbon buildup. I’ve seen chainsaws rendered virtually useless due to neglected air filters.

Understanding Air Filter Types

The Craftsman 917.353710 typically uses a foam or paper air filter. Foam filters are reusable and can be cleaned, while paper filters are generally disposable and should be replaced when dirty.

Cleaning a Foam Air Filter

Here’s how I clean a foam air filter:

1. Remove the Air Filter Cover: Locate the air filter cover on the chainsaw and remove it. This usually involves unscrewing a few fasteners or releasing a latch.
2. Remove the Air Filter: Carefully remove the air filter from its housing.
3. Clean the Air Filter: Wash the air filter in warm, soapy water. Use a mild detergent and avoid harsh chemicals that could damage the foam.
4. Rinse Thoroughly: Rinse the air filter thoroughly with clean water to remove all traces of soap.
5. Dry Completely: Allow the air filter to dry completely before reinstalling it. You can gently squeeze out excess water, but avoid twisting or wringing the filter, as this could damage it. I usually let it air dry overnight.
6. Oil Lightly: Once the air filter is dry, lightly oil it with air filter oil. This helps trap dirt and debris. Don’t over-oil the filter, as this can restrict airflow. I typically use a spray-on air filter oil and apply a light, even coating.
7. Reinstall the Air Filter: Reinstall the air filter into its housing and secure the air filter cover.

Replacing a Paper Air Filter

Replacing a paper air filter is even simpler:

1. Remove the Air Filter Cover: Locate the air filter cover on the chainsaw and remove it.
2. Remove the Air Filter: Carefully remove the old air filter from its housing.
3. Install a New Air Filter: Install a new, clean air filter into its housing.
4. Reinstall the Air Filter Cover: Secure the air filter cover.

Pro Tip: Regular Inspection and Cleaning

I make it a habit to inspect the air filter every time I refuel the chainsaw. If it’s visibly dirty, I clean or replace it immediately. Regular inspection and cleaning will help maintain optimal engine performance and extend the life of your chainsaw.

Case Study: The Power of a Clean Air Filter

I was once helping a friend clear some brush on his property. His chainsaw was running poorly, lacking power and stalling frequently. After checking the fuel and spark plug, I discovered that the air filter was completely clogged with dirt and debris. We cleaned the air filter, and the chainsaw immediately regained its power and ran smoothly. This simple fix saved us a lot of time and frustration.

Strategic Advantage: Air Filter Maintenance Schedule

Develop a regular air filter maintenance schedule. For heavy use, clean or replace the air filter weekly. For occasional use, clean or replace it monthly. This will help ensure that your chainsaw is always running at its best.

3. Spark Plug Perfection: Inspection, Cleaning, and Replacement

The spark plug is responsible for igniting the fuel-air mixture in the engine’s cylinder. A faulty or fouled spark plug can cause difficult starting, poor performance, and misfires. I’ve encountered countless chainsaw problems that were traced back to a simple spark plug issue.

Understanding Spark Plug Function

The spark plug creates a spark that ignites the fuel-air mixture, initiating the combustion process that drives the engine. Over time, spark plugs can become fouled with carbon deposits, oil, or other contaminants. The gap between the electrodes can also widen, reducing the spark’s intensity.

Inspecting the Spark Plug

Here’s how I inspect a spark plug:

1. Locate the Spark Plug: The spark plug is typically located on the top or side of the engine, under a protective boot.
2. Remove the Spark Plug Boot: Carefully pull the spark plug boot off the spark plug.
3. Remove the Spark Plug: Use a spark plug wrench to loosen and remove the spark plug.

4. Inspect the Spark Plug: Examine the spark plug for signs of wear, damage, or fouling. Look for:

   • Carbon Deposits: Black, sooty deposits indicate a rich fuel mixture or excessive oil consumption.
   • Oil Fouling: Wet, oily deposits indicate oil leaking into the combustion chamber.
   • Worn Electrodes: Rounded or eroded electrodes indicate normal wear and tear.
   • Cracked Insulator: Cracks in the ceramic insulator indicate damage and the need for replacement.
   • Clean the Spark Plug (If Necessary): If the spark plug is only slightly fouled with carbon deposits, you can clean it with a wire brush or spark plug cleaner. Be careful not to damage the electrodes.

Adjusting the Spark Plug Gap

The spark plug gap is the distance between the center electrode and the ground electrode. The correct spark plug gap is crucial for proper ignition. The manufacturer’s recommended spark plug gap for the Craftsman 917.353710 is typically 0.025 inches (0.635 mm).

Here’s how I adjust the spark plug gap:

1. Use a Spark Plug Gap Tool: Use a spark plug gap tool to measure the gap between the electrodes.
2. Adjust the Gap: If the gap is too wide, gently tap the ground electrode against a hard surface to close the gap. If the gap is too narrow, use the spark plug gap tool to carefully pry the ground electrode open.
3. Re-Measure the Gap: Re-measure the gap to ensure that it is within the specified range.

Replacing the Spark Plug

If the spark plug is severely fouled, damaged, or worn, it’s best to replace it.

1. Install a New Spark Plug: Install a new spark plug of the correct type and heat range. Consult the owner’s manual for the correct spark plug specification.
2. Tighten the Spark Plug: Tighten the spark plug to the manufacturer’s recommended torque specification. If you don’t have a torque wrench, tighten the spark plug snugly, but avoid over-tightening it, as this could damage the threads in the cylinder head.
3. Reinstall the Spark Plug Boot: Reinstall the spark plug boot onto the spark plug.

Pro Tip: Keep a Spare Spark Plug on Hand

I always keep a spare spark plug on hand, along with a spark plug wrench and gap tool. This allows me to quickly replace a faulty spark plug in the field, minimizing downtime.

Case Study: The Misfiring Chainsaw

I was once cutting firewood with a friend when his chainsaw started misfiring and losing power. We checked the fuel and air filter, but they were both fine. After removing the spark plug, we discovered that it was heavily fouled with carbon deposits. We cleaned the spark plug, adjusted the gap, and the chainsaw ran perfectly. This simple fix saved us a lot of time and effort.

Strategic Advantage: Spark Plug Maintenance Schedule

Replace the spark plug annually or every 100 hours of use, whichever comes first. Regular spark plug replacement will help maintain optimal engine performance and prevent starting problems.

Measurements and Specifications:

• Spark Plug Gap: 0.025 inches (0.635 mm)
• Replacement Frequency: Annually or every 100 hours of use
• Tools: Spark plug wrench, spark plug gap tool

4. Chain Champion: Sharpening and Tensioning the Chain

A sharp chain is crucial for efficient cutting and safe operation. A dull chain requires more force to cut, which can lead to operator fatigue, increased fuel consumption, and a higher risk of kickback. I’ve experienced the frustration of working with a dull chain, and I can attest to the significant difference a sharp chain makes.

Understanding Chain Anatomy

The chainsaw chain consists of several components, including:

• Cutters: The cutters are the sharp teeth that do the actual cutting.
• Tie Straps: The tie straps connect the cutters and drive links.
• Drive Links: The drive links engage with the sprocket on the chainsaw and pull the chain around the bar.
• Depth Gauges (Rakers): The depth gauges control the amount of wood that the cutters can remove.

Sharpening the Chain

Sharpening the chain involves restoring the cutting edges of the cutters. There are two main methods for sharpening a chainsaw chain:

• Hand Sharpening: Hand sharpening involves using a round file and a file guide to sharpen each cutter individually.
• Electric Chain Sharpener: An electric chain sharpener uses a grinding wheel to sharpen the cutters quickly and accurately.

Hand Sharpening (My Preferred Method)

I prefer hand sharpening because it allows me to maintain the chain’s original cutting angles and depth. Here’s my step-by-step method:

1. Secure the Chainsaw: Secure the chainsaw in a vise or on a stable surface.
2. Use a File Guide: Use a file guide that matches the chain’s pitch (the distance between the chain’s rivets). The file guide helps maintain the correct sharpening angle and depth.
3. Sharpen Each Cutter: Sharpen each cutter individually, using smooth, even strokes. Follow the angle markings on the file guide.
4. Maintain Consistent Pressure: Maintain consistent pressure on the file and avoid applying too much force.
5. Sharpen All Cutters: Sharpen all cutters on one side of the chain, then rotate the chainsaw and sharpen the cutters on the other side.
6. Check Depth Gauges: Use a depth gauge tool to check the height of the depth gauges (rakers). The depth gauges should be slightly lower than the cutters.
7. File Down Depth Gauges (If Necessary): If the depth gauges are too high, file them down using a flat file.

Chain Tensioning

Proper chain tension is crucial for safe and efficient operation. A chain that is too loose can derail from the bar, while a chain that is too tight can cause excessive wear and tear on the bar and sprocket.

Here’s how I tension the chain:

1. Loosen the Bar Nuts: Loosen the bar nuts that secure the bar to the chainsaw.
2. Adjust the Tensioning Screw: Use the chain tensioning screw to adjust the chain tension. The chain should be snug against the bar, but you should still be able to pull it around the bar by hand.
3. Tighten the Bar Nuts: Tighten the bar nuts securely.
4. Check the Tension: Check the chain tension again after tightening the bar nuts.

Pro Tip: Sharpen Frequently

I sharpen my chainsaw chain frequently, usually after every few tanks of fuel. A sharp chain cuts faster, requires less effort, and is safer to use. I also carry a small file and file guide with me in the field so I can touch up the chain as needed.

Case Study: The Importance of a Sharp Chain

I was once felling a large oak tree with a dull chain. The chainsaw was struggling to cut through the wood, and I was forced to apply excessive force. Suddenly, the chainsaw kicked back violently, nearly causing me to lose control. Fortunately, I was able to react quickly and avoid injury. This incident reinforced the importance of using a sharp chain and practicing proper chainsaw safety techniques.

Strategic Advantage: Chain Sharpening Schedule

Develop a regular chain sharpening schedule. Sharpen the chain after every few tanks of fuel or whenever you notice a decrease in cutting performance. This will help ensure that your chainsaw is always cutting at its best.

Measurements and Specifications:

• Chain Pitch: Consult the owner’s manual for the correct chain pitch.
• File Size: Use a round file that matches the chain’s pitch.
• Depth Gauge Setting: The depth gauges should be slightly lower than the cutters.
• Tension: The chain should be snug against the bar, but you should still be able to pull it around the bar by hand.

5. Bar and Beyond: Maintaining the Bar and Oiling System

The chainsaw bar guides the chain and supports it during cutting. The oiling system lubricates the chain and bar, reducing friction and preventing wear. Proper maintenance of the bar and oiling system is essential for extending the life of your chainsaw.

Understanding Bar Anatomy

The chainsaw bar consists of several components, including:

• Rails: The rails are the edges of the bar that the chain rides on.
• Sprocket Tip: The sprocket tip is a small wheel at the end of the bar that helps guide the chain.
• Oil Hole: The oil hole is a small opening on the bar that allows oil to lubricate the chain.

Maintaining the Bar

Here’s how I maintain the chainsaw bar:

1. Clean the Bar: Clean the bar regularly with a wire brush to remove dirt, debris, and sawdust.
2. Check the Rails: Check the rails for wear and damage. If the rails are worn or damaged, they can be dressed with a bar rail dressing tool or replaced.
3. Clean the Oil Hole: Clean the oil hole with a small wire or needle to ensure that it is free of obstructions.
4. Flip the Bar: Flip the bar periodically to distribute wear evenly.

Maintaining the Oiling System

The oiling system lubricates the chain and bar, reducing friction and preventing wear.

Here’s how I maintain the oiling system:

1. Check the Oil Level: Check the oil level regularly and refill as needed.
2. Use the Correct Oil: Use chainsaw bar and chain oil specifically designed for chainsaw lubrication. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication. I prefer using a high-quality, biodegradable bar and chain oil.
3. Adjust the Oil Flow (If Possible): Some chainsaws have an adjustable oil flow. Adjust the oil flow to match the cutting conditions. For heavy cutting, increase the oil flow. For light cutting, reduce the oil flow.
4. Clean the Oiler: Periodically clean the oiler to remove dirt and debris.

Pro Tip: Bar and Chain Oil Selection

I’ve found that using a high-quality bar and chain oil makes a significant difference in the performance and longevity of the chainsaw. I prefer using a synthetic or semi-synthetic oil, as it provides better lubrication and reduces wear. I also look for oils that contain tackifiers, which help the oil adhere to the chain and bar.

Case Study: The Oiling System Failure

I was once cutting firewood with a friend when his chainsaw suddenly started smoking and seizing up. We quickly shut off the chainsaw and discovered that the oiling system had failed. The chain and bar were completely dry, and the friction had caused the metal to overheat and seize. This experience reinforced the importance of regularly checking the oil level and maintaining the oiling system.

Strategic Advantage: Bar and Chain Maintenance Schedule

Develop a regular bar and chain maintenance schedule. Clean the bar and check the oil level every time you refuel the chainsaw. Dress the rails and clean the oil hole monthly. Replace the bar as needed. This will help ensure that your chainsaw is always running smoothly and efficiently.
