The Stihl MS290: A Woodcutter’s Reliable Friend

The Stihl MS290 Farm Boss is renowned for its durability and power. It bridges the gap between homeowner saws and professional models, making it a popular choice for those who need a reliable chainsaw for regular use. Its 56.5cc engine delivers ample power for felling small trees, limbing, bucking firewood, and general property maintenance. However, like any piece of machinery, understanding its quirks and proper starting procedures is crucial for optimal performance and longevity.

The Starting Sequence: A Step-by-Step Guide

Starting a Stihl MS290 chainsaw might seem straightforward, but following a specific sequence is essential, especially when the engine is cold. Here’s a detailed breakdown:

Step 1: Safety First

Before even thinking about pulling the starter cord, ensure you’re wearing appropriate safety gear. This includes:

• Safety Glasses: Protect your eyes from flying debris.
• Hearing Protection: Chainsaws are loud; protect your hearing.
• Gloves: Provide a better grip and protect your hands.
• Chaps: Essential for leg protection in case of kickback.
• Sturdy Boots: Provide ankle support and protection.

Also, ensure the chainsaw is on a stable, flat surface, away from flammable materials. Double-check that the chain brake is engaged (pushed forward).

Step 2: Fuel and Oil Check

Make sure the fuel tank is filled with the correct fuel mixture (typically a 50:1 ratio of gasoline to two-stroke oil). Stihl recommends using their own brand of two-stroke oil, but any high-quality two-stroke oil meeting the JASO FD or ISO-L-EGD specifications will work. I always pre-mix my fuel in a separate container to ensure the correct ratio. Using the wrong fuel mixture can lead to engine damage and starting problems.

Also, check the bar oil reservoir and top it off if necessary. The bar oil lubricates the chain and bar, preventing excessive wear and heat buildup.

Step 3: Activating the Choke

The choke restricts airflow to the carburetor, enriching the fuel mixture for cold starting. On the MS290, the choke lever is usually located on the left side of the engine, near the carburetor.

• Cold Start: Pull the choke lever all the way out. This closes the choke completely.
• Warm Start: For a warm engine, the choke lever should be in the run position (pushed all the way in).

Step 4: Priming the Carburetor

The primer bulb is a small, clear bulb located near the carburetor. Press it firmly several times (usually 5-6 times) until you see fuel flowing through the bulb. This primes the carburetor by drawing fuel into the system, making it easier to start. Don’t over-prime, as this can flood the engine.

Step 5: Setting the Master Control Lever

The master control lever (also known as the on/off switch) controls the ignition. Slide it to the “Start” or “Run” position. This allows the spark plug to ignite the fuel mixture.

Step 6: Pulling the Starter Cord

This is where technique matters.

• Stance: Place the chainsaw firmly on the ground, holding the front handle with your left hand. Place your right foot through the rear handle for stability.
• Grip: Grasp the starter handle firmly with your right hand.
• Pull: Pull the starter cord slowly and steadily until you feel resistance. Then, give it a sharp, full pull. Avoid yanking the cord excessively, as this can damage the starter mechanism.

Step 7: Adjusting the Choke (if necessary)

After a few pulls, the engine should sputter or attempt to start. At this point, push the choke lever in to the half-choke position (usually the middle position). This provides a slightly leaner fuel mixture. Continue pulling the starter cord until the engine starts and runs roughly.

Step 8: Warming Up

Once the engine starts, let it run for a minute or two to warm up. This allows the engine to reach its operating temperature and ensures smooth running. You may need to gently feather the throttle to keep the engine from stalling during the warm-up period.

Step 9: Disengaging the Chain Brake

Once the engine is warmed up, disengage the chain brake by pulling the front hand guard back towards you until it clicks into place. Now your Stihl MS290 is ready to cut!

1. No Spark

A lack of spark is a common cause of starting problems. Here’s how to check for spark:

• Spark Plug Inspection: Remove the spark plug and inspect it. Look for cracks, carbon buildup, or a wet appearance. A fouled or damaged spark plug won’t produce a spark. Clean the spark plug with a wire brush or replace it with a new one (Champion RCJ6Y or NGK BPMR7A are common replacements). The gap should be set to 0.020 inches.
• Spark Tester: Use a spark tester to check for spark. Connect the tester to the spark plug wire and ground the tester. Pull the starter cord. If you see a spark, the ignition system is likely working. If there’s no spark, the problem could be the ignition coil, the kill switch, or the wiring.
• Ignition Coil: The ignition coil generates the high voltage needed to create a spark. If the spark plug is good and there’s no spark, the ignition coil may be faulty. Use a multimeter to test the coil’s resistance. Refer to the Stihl MS290 service manual for the correct resistance values. A faulty ignition coil will need to be replaced.
• Kill Switch: The kill switch grounds the ignition system, preventing the engine from starting. If the kill switch is faulty or the wiring is damaged, it can prevent the engine from starting even when it’s in the “Run” position. Disconnect the kill switch wire from the ignition coil and try starting the engine. If it starts, the kill switch is the problem.
• Flywheel Key: The flywheel key aligns the flywheel with the crankshaft. If the key is sheared, the timing will be off, preventing the engine from starting. Remove the flywheel and inspect the key. If it’s damaged, replace it.

Personal Story: I once spent an entire afternoon trying to start my MS290, only to discover that the spark plug was cracked. It looked fine at first glance, but a closer inspection revealed a hairline crack that was preventing it from firing. A new spark plug solved the problem instantly. It taught me the importance of thorough inspection.

2. Fuel Delivery Problems

If the engine is getting spark but still won’t start, the problem could be fuel delivery. Here’s what to check:

• Fuel Tank Vent: The fuel tank vent allows air to enter the tank, preventing a vacuum from forming and ensuring fuel flows freely. If the vent is clogged, fuel won’t reach the carburetor. Clean the vent with compressed air or a small wire.
• Fuel Filter: The fuel filter prevents debris from entering the carburetor. A clogged fuel filter will restrict fuel flow. Replace the fuel filter regularly (at least once a year).
• Fuel Lines: Inspect the fuel lines for cracks, leaks, or kinks. Damaged fuel lines can prevent fuel from reaching the carburetor. Replace any damaged fuel lines.
• Carburetor: The carburetor mixes fuel and air in the correct proportions for combustion. A dirty or clogged carburetor can cause starting problems. Clean the carburetor with carburetor cleaner. If the carburetor is heavily soiled, you may need to disassemble it and clean each part individually. Carburetor rebuild kits are available and can be a cost-effective way to restore a carburetor to like-new condition.
• Impulse Line: The impulse line connects the crankcase to the carburetor and provides the pressure pulse needed to pump fuel. A cracked or leaking impulse line can prevent the carburetor from drawing fuel. Inspect the impulse line for damage and replace it if necessary.

Data Point: A study by the Outdoor Power Equipment Institute (OPEI) found that approximately 60% of chainsaw starting problems are related to fuel issues, highlighting the importance of proper fuel maintenance.

3. Compression Issues

Low compression can also prevent an engine from starting. Here’s how to check for compression:

• Compression Tester: Use a compression tester to measure the engine’s compression. Remove the spark plug and screw the compression tester into the spark plug hole. Pull the starter cord several times and note the reading on the tester. The Stihl MS290 should have a compression reading of at least 120 PSI.
• Piston and Cylinder: If the compression is low, the problem could be worn piston rings, a damaged piston, or a scored cylinder. Remove the muffler and inspect the piston and cylinder for damage. If there’s significant damage, the engine may need to be rebuilt.

Unique Insight: I once had an MS290 that was incredibly hard to start, and I eventually discovered that a small piece of carbon had broken off the piston and lodged itself between the piston and cylinder wall, creating a significant leak. It’s a rare occurrence, but it highlights the importance of checking for even minor damage.

4. Flooding

Over-priming or excessive choking can flood the engine, making it difficult to start. If you suspect the engine is flooded, follow these steps:

• Remove the Spark Plug: Remove the spark plug and pull the starter cord several times to clear excess fuel from the cylinder.
• Dry the Spark Plug: Dry the spark plug with a clean cloth or paper towel.
• Reinstall the Spark Plug: Reinstall the spark plug and try starting the engine without using the choke.

5. Other Potential Issues

• Incorrect Fuel Mixture: Using the wrong fuel mixture (too much oil or not enough oil) can cause starting problems. Always use the correct fuel mixture (50:1).
• Old Fuel: Old fuel can degrade and lose its octane rating, making it difficult to start the engine. Use fresh fuel (less than 30 days old).
• Clogged Muffler: A clogged muffler can restrict exhaust flow and prevent the engine from starting. Remove the muffler and inspect it for carbon buildup. Clean the muffler with a wire brush or replace it if necessary.

Wood Anatomy and Properties: Understanding Your Material

Understanding the wood you’re cutting is crucial for efficient and safe woodcutting. Different wood species have different densities, grain patterns, and moisture contents, which affect how they cut and split.

Hardwood vs. Softwood

• Hardwoods: Typically deciduous trees (trees that lose their leaves in the fall) such as oak, maple, and ash. Hardwoods are generally denser and harder to cut than softwoods. They also burn hotter and longer, making them ideal for firewood.
• Softwoods: Typically coniferous trees (trees that have needles) such as pine, fir, and spruce. Softwoods are generally less dense and easier to cut than hardwoods. They ignite easily and burn quickly, making them suitable for kindling.

Comparison Table:

Moisture Content

The moisture content of wood significantly affects its weight, cutting ease, and burning characteristics. Freshly cut (green) wood can have a moisture content of 50% or higher. Seasoned (dried) wood has a moisture content of 20% or less.

• Green Wood: Heavy, difficult to cut, and doesn’t burn well.
• Seasoned Wood: Lighter, easier to cut, and burns efficiently.

Data Point: According to the U.S. Department of Energy, burning seasoned firewood can increase heating efficiency by up to 30% compared to burning green firewood.

Determining Moisture Content

• Moisture Meter: Use a moisture meter to accurately measure the moisture content of wood.
• Visual Inspection: Look for cracks and checks (splits) in the end grain of the wood, which indicate drying.
• Weight: Seasoned wood is significantly lighter than green wood.

Actionable Advice: I recommend investing in a good quality chainsaw sharpener and learning how to sharpen your chain properly. A sharp chain makes a huge difference in cutting efficiency and safety.

Firewood Seasoning Techniques and Safety Considerations

Seasoning firewood is crucial for efficient burning and reducing creosote buildup in your chimney.

Seasoning Techniques

• Stacking: Stack firewood in a single row, off the ground, in a sunny and windy location. This allows for maximum air circulation.
• Covering: Cover the top of the firewood pile to protect it from rain and snow. Leave the sides open for ventilation.
• Time: Season firewood for at least six months, and preferably a year or more.

Safety Considerations

• Personal Protective Equipment: Always wear appropriate safety gear when handling firewood, including gloves, safety glasses, and sturdy boots.
• Lifting Techniques: Use proper lifting techniques to avoid back injuries. Bend your knees and keep your back straight.
• Stacking Stability: Stack firewood carefully to prevent it from collapsing.
• Pest Control: Be aware of potential pests, such as insects and rodents, that may be attracted to firewood.

Case Study: I conducted a small experiment comparing the burning efficiency of firewood seasoned for six months versus firewood seasoned for one year. The firewood seasoned for one year burned significantly hotter and longer, and produced less smoke. This confirmed the importance of proper seasoning.

Project Planning and Execution: From Tree to Firewood

Planning your firewood project is essential for efficiency and safety.

Step 1: Assessment

• Determine Your Needs: How much firewood do you need for the winter?
• Assess Your Resources: Do you have access to trees? Do you have the necessary tools and equipment?
