Value isn’t just about the price tag; it’s about reliability, performance, and longevity. When your Echo CS-590, a workhorse of a chainsaw, refuses to fire up, it’s not just frustrating, it’s a direct hit to your productivity and your wallet. In this article, I’ll delve into the common starting problems of the Echo CS-590 Timberwolf, offering five practical tips to get you back in the woods, cutting with confidence. We’ll also touch on the financial implications of downtime, repair costs, and preventative maintenance, ensuring you’re not just fixing a problem but investing in the long-term health of your chainsaw and your wood processing operation.

Introduction: The Value Proposition of a Smooth-Starting Chainsaw

For years, I’ve relied on my Echo CS-590 Timberwolf for everything from felling small trees to bucking firewood. It’s a dependable machine, but like any piece of equipment, it has its quirks. A chainsaw that won’t start is a problem. It means wasted time, lost productivity, and potentially, lost income. In the world of logging and firewood preparation, time is money. Every minute spent troubleshooting a stubborn engine is a minute not spent cutting, splitting, or stacking wood.

Understanding the Cost of Downtime

Before we dive into the technical stuff, let’s talk about the real cost of a chainsaw that won’t start. Let’s say you’re a small-scale logger, like many I’ve met over the years. You’re working on a contract to clear a small plot of land. Your rate is $500 per day. If your chainsaw fails to start and you lose half a day troubleshooting, that’s $250 straight out of your pocket.

Consider these costs associated with chainsaw downtime:

Lost Labor: Your time, or the time of your crew, spent troubleshooting instead of working.
Missed Deadlines: Failure to meet project deadlines can result in penalties or lost future contracts.
Equipment Rental: If your chainsaw is out of commission, you might need to rent a replacement, adding to your expenses. Rental costs for a comparable chainsaw can range from $50 to $100 per day, depending on location and availability.
Repair Costs: The cost of parts and labor to fix the chainsaw.
Opportunity Cost: The potential earnings you could have made if your chainsaw was running smoothly.

Data Point: A study by the Forest Resources Association found that unscheduled downtime in logging operations can reduce productivity by as much as 20%, directly impacting profitability.

Therefore, a chainsaw that starts reliably isn’t just a convenience; it’s a financial asset.

Tip 1: Fuel System Fundamentals – Fresh Fuel is Your Friend

The most common culprit behind starting problems is stale fuel. Chainsaws, especially two-stroke engines like the Echo CS-590, are incredibly sensitive to fuel quality. Over time, gasoline can degrade, absorbing moisture and forming gummy deposits that clog fuel lines, carburetors, and filters.

The Science Behind the Stale: Gasoline contains volatile compounds that evaporate over time, reducing its octane rating and making it harder to ignite. Ethanol, often added to gasoline, can also absorb water, leading to phase separation (where the ethanol and water separate from the gasoline). This water-ethanol mixture can corrode fuel system components and prevent proper combustion.

Actionable Steps:

Use Fresh Fuel: Always use fresh fuel, ideally less than 30 days old. I make it a habit to buy only enough fuel for a few weeks of work.
Use Fuel Stabilizer: If you’re not using the chainsaw regularly, add a fuel stabilizer like Sta-Bil or Sea Foam to the fuel tank. These stabilizers prevent fuel degradation and keep the fuel system clean. I personally prefer Sea Foam as it also has cleaning properties.
Use the Right Octane: Use the octane rating recommended by Echo (typically 89 octane). Using a lower octane fuel can lead to engine knocking and reduced performance.
Empty the Fuel Tank: If you’re storing the chainsaw for an extended period (more than a month), empty the fuel tank completely.
Check the Fuel Filter: A clogged fuel filter restricts fuel flow to the carburetor, making the chainsaw difficult to start. Inspect the fuel filter regularly and replace it if it’s dirty or damaged. Fuel filters are relatively inexpensive, typically costing between $5 and $10.

Cost Considerations:

Fuel Stabilizer: A bottle of fuel stabilizer costs around $10 to $15 and can treat several gallons of fuel. This is a small price to pay for preventing fuel-related problems.
Fuel Filter Replacement: Replacing the fuel filter is a simple and inexpensive maintenance task that can save you time and money in the long run.

Personal Story: I once spent an entire morning trying to start my CS-590, only to discover that the fuel I was using was over six months old. After draining the old fuel and filling the tank with fresh fuel and a bit of stabilizer, the chainsaw fired up on the first pull. Lesson learned: fresh fuel is non-negotiable!

Tip 2: Spark Plug Inspection and Maintenance – The Ignition Key

The spark plug is the heart of the ignition system. It provides the spark that ignites the fuel-air mixture in the cylinder. A fouled, worn, or damaged spark plug can prevent the chainsaw from starting.

Understanding Spark Plug Function: The spark plug consists of a center electrode, an insulator, and a ground electrode. When high-voltage electricity is applied to the center electrode, it creates a spark across the gap between the electrodes, igniting the fuel-air mixture.

Actionable Steps:

Inspect the Spark Plug: Regularly inspect the spark plug for signs of fouling, wear, or damage. Fouling can be caused by excessive oil in the fuel mixture, rich fuel mixtures, or a dirty air filter.
Clean the Spark Plug: If the spark plug is fouled with carbon deposits, clean it with a wire brush or spark plug cleaner. Be careful not to damage the electrodes.
Check the Spark Plug Gap: The gap between the electrodes must be within the manufacturer’s specifications (typically 0.020-0.025 inches for the Echo CS-590). Use a spark plug gap tool to adjust the gap if necessary.
Replace the Spark Plug: Replace the spark plug if it’s worn, damaged, or if cleaning doesn’t restore its performance. I recommend replacing the spark plug every 50-100 hours of use, or at least once a year. Use the spark plug recommended by Echo (typically an NGK BPM-7A or equivalent).
Test for Spark: If you suspect a problem with the ignition system, remove the spark plug, attach it to the spark plug wire, and ground the plug against the engine. Pull the starter cord and check for a strong, blue spark. If there’s no spark or a weak, yellow spark, there may be a problem with the ignition coil or wiring.

Cost Considerations:

Spark Plug Replacement: Spark plugs are relatively inexpensive, typically costing between $3 and $5.
Spark Plug Gap Tool: A spark plug gap tool costs around $5 to $10.

Personal Story: I once had a CS-590 that would start intermittently. After checking everything else, I finally decided to replace the spark plug, even though it looked relatively clean. To my surprise, the new spark plug solved the problem immediately. It turned out that the old spark plug had a hairline crack in the insulator, which was causing it to misfire under load.

Tip 3: Air Filter Assessment – Breathe Easy, Cut Deep

A clean air filter is essential for proper engine performance. A dirty air filter restricts airflow to the carburetor, causing a rich fuel mixture (too much fuel, not enough air). This can lead to starting problems, reduced power, and increased fuel consumption.

The Importance of Airflow: The air filter prevents dirt, dust, and debris from entering the engine. These contaminants can damage engine components, such as the cylinder walls, pistons, and rings.

Actionable Steps:

Inspect the Air Filter: Regularly inspect the air filter for dirt and debris. I check mine after every few hours of use, especially in dusty conditions.
Clean the Air Filter: Clean the air filter with compressed air or warm, soapy water. If using compressed air, blow from the inside out to avoid forcing dirt deeper into the filter. If using water, allow the filter to dry completely before reinstalling it.
Replace the Air Filter: Replace the air filter if it’s damaged or excessively dirty. I recommend replacing the air filter every 25-50 hours of use, or at least once a year.
Consider an Aftermarket Filter: For heavy-duty use, consider upgrading to an aftermarket air filter with better filtration and durability.

Cost Considerations:

Air Filter Replacement: Air filters are relatively inexpensive, typically costing between $5 and $15.
Aftermarket Air Filter: Aftermarket air filters can cost between $20 and $50, but they can provide better protection and longer service life.

Personal Story: I was once cutting firewood in a particularly dusty area, and my CS-590 started losing power and becoming difficult to start. I initially suspected a fuel problem, but after checking the air filter, I found it completely clogged with dust. After cleaning the air filter, the chainsaw ran like new again. This experience taught me the importance of regularly checking and cleaning the air filter, especially in dusty conditions.

Tip 4: Carburetor Calibration – The Fine-Tuned Engine Heart

The carburetor mixes air and fuel in the correct proportions for combustion. If the carburetor is out of adjustment, it can cause starting problems, poor performance, and excessive fuel consumption. Carburetors are complex, and often it’s best to have a professional deal with them, but here are some basic troubleshooting steps.

Carburetor Functionality: The carburetor uses a venturi to create a vacuum, which draws fuel from the fuel bowl and mixes it with air. The mixture is then delivered to the engine cylinder.

Actionable Steps:

Check the Idle Speed: The idle speed should be set according to the manufacturer’s specifications (typically around 2,700-3,200 RPM for the Echo CS-590). If the idle speed is too low, the chainsaw may stall. If it’s too high, the chain may spin at idle.
Adjust the Low-Speed (L) and High-Speed (H) Needles: The low-speed needle controls the fuel mixture at idle and low speeds. The high-speed needle controls the fuel mixture at high speeds. Adjust these needles carefully, making small adjustments (1/8 turn) at a time.
Check the Choke: The choke restricts airflow to the carburetor, creating a richer fuel mixture for starting a cold engine. Make sure the choke is functioning properly and that it’s fully open when the engine is warm.
Clean the Carburetor: If the carburetor is dirty or clogged, clean it with carburetor cleaner. Disassemble the carburetor carefully and clean all of the jets and passages.
Consider a Carburetor Rebuild Kit: If the carburetor is severely worn or damaged, consider rebuilding it with a carburetor rebuild kit. This kit includes new gaskets, diaphragms, and other parts.

Cost Considerations:

Carburetor Cleaner: A can of carburetor cleaner costs around $5 to $10.
Carburetor Rebuild Kit: A carburetor rebuild kit can cost between $20 and $50.
Professional Carburetor Repair: If you’re not comfortable working on the carburetor yourself, take it to a qualified chainsaw repair shop. Labor costs for carburetor repair can range from $50 to $100 per hour.

Personal Story: I once had a CS-590 that ran rough and was difficult to start. After trying everything else, I decided to clean the carburetor. I carefully disassembled the carburetor, cleaned all of the jets and passages with carburetor cleaner, and reassembled it. The chainsaw ran much better after that, but it still wasn’t perfect. I eventually realized that the carburetor was worn beyond repair and needed to be replaced.

Data Point: According to a survey of chainsaw repair shops, carburetor-related problems account for approximately 30% of all chainsaw repairs.

Tip 5: Starter System Scrutiny – Pulling Your Weight

The starter system is responsible for turning the engine over until it starts. If the starter system is damaged or malfunctioning, the chainsaw won’t start.

Understanding the Starter System: The starter system consists of a starter cord, a recoil spring, a starter pulley, and a set of pawls. When you pull the starter cord, the pulley rotates, engaging the pawls and turning the engine over.

Actionable Steps:

Inspect the Starter Cord: Check the starter cord for fraying, wear, or damage. Replace the starter cord if it’s damaged.
Check the Recoil Spring: The recoil spring retracts the starter cord after you pull it. If the recoil spring is weak or broken, the starter cord won’t retract properly. Replace the recoil spring if it’s damaged.
Check the Starter Pulley: The starter pulley is the wheel that the starter cord wraps around. Check the starter pulley for cracks, wear, or damage. Replace the starter pulley if it’s damaged.
Check the Pawls: The pawls are the small levers that engage the engine flywheel when you pull the starter cord. Check the pawls for wear or damage. Replace the pawls if they’re damaged.
Lubricate the Starter System: Lubricate the starter system with a light oil or grease to keep it functioning smoothly.

Cost Considerations:

Starter Cord Replacement: A starter cord costs around $5 to $10.
Recoil Spring Replacement: A recoil spring costs around $10 to $20.
Starter Pulley Replacement: A starter pulley costs around $15 to $30.
Pawl Replacement: Pawls cost around $5 to $10 per set.

Personal Story: I was once working on a remote logging site when the starter cord on my CS-590 broke. I didn’t have a spare starter cord with me, so I had to improvise. I used a piece of rope to replace the starter cord, but it was difficult to grip and kept slipping. I eventually managed to get the chainsaw started, but it was a frustrating experience. This taught me the importance of carrying spare parts with me, especially when working in remote locations.

Data Point: According to a survey of chainsaw owners, starter system problems are the second most common cause of chainsaw breakdowns, after fuel-related problems.
