Chainsaw Stihl MS290 Troubleshooting Tips (5 Pro Fixes) & The Real Cost of Firewood

Let’s face it, a Stihl MS290 is a workhorse. It’s the kind of chainsaw that gets passed down, sees years of service, and generally keeps on ticking. But even the most reliable machines have their hiccups. This article isn’t just about fixing those hiccups; it’s about understanding the real cost of keeping that saw running, and how it impacts your wood processing or firewood operation. I’ve spent years felling trees, bucking logs, and splitting wood – sometimes professionally, sometimes just for my own winter stash. I’ve learned that a well-maintained saw and a smart budget are essential for success.

Why This Matters: More Than Just a Fix

Before we dive into the troubleshooting, let’s talk about why this matters. A malfunctioning chainsaw isn’t just an inconvenience; it’s a drain on your time and resources. It can impact your productivity, increase your fuel consumption, and even lead to more serious (and costly) repairs down the line. Plus, a poorly running saw is a safety hazard. This article will guide you through common MS290 issues, but it will also give you the tools to understand the bigger picture: the true cost of processing wood.

Stihl MS290 Troubleshooting: 5 Common Problems and Pro Fixes

Here are five of the most common problems I’ve encountered with the Stihl MS290, along with the troubleshooting steps and potential fixes:

1. Chainsaw Won’t Start

This is the most frustrating problem, right? You’re ready to get to work, and the saw just refuses to fire up. Here’s a systematic approach:

Fuel Check: This sounds obvious, but it’s the first thing to check. Is there fuel in the tank? Is it the correct fuel mixture (50:1 ratio of gasoline to 2-cycle oil is standard for the MS290)? Old fuel is a common culprit. Gasoline degrades over time, especially when mixed with oil. If the fuel is more than a month old, drain it and refill with fresh fuel. Cost of fresh fuel: Approximately $4-$6 per gallon, depending on location and grade.
Spark Plug: A fouled or worn spark plug is another frequent cause of starting problems. Remove the spark plug and inspect it. Look for cracks in the porcelain, excessive carbon buildup, or a wet, oily appearance. If it looks bad, replace it. Even if it looks okay, it’s worth cleaning it with a wire brush or spark plug cleaner. Cost of a new spark plug: $5-$10. To test if the spark plug is working, ground the plug against the engine block while pulling the starter cord. Look for a strong, blue spark. A weak or absent spark indicates a bad plug or a problem with the ignition system.
Air Filter: A clogged air filter restricts airflow to the engine, making it difficult to start. Remove the air filter and inspect it. If it’s dirty, clean it with warm, soapy water. Allow it to dry completely before reinstalling. If it’s excessively dirty or damaged, replace it. Cost of a new air filter: $8-$15. I’ve found that investing in a few extra air filters is a smart move, especially if you’re working in dusty conditions.
Carburetor: The carburetor mixes fuel and air for combustion. If the saw has been sitting for a while, the carburetor jets can become clogged with varnish or debris. Try using carburetor cleaner to flush out the carburetor. If that doesn’t work, you may need to disassemble the carburetor and clean it thoroughly. This is a more complex task, and if you’re not comfortable with it, it’s best to take the saw to a qualified mechanic. Cost of carburetor cleaner: $5-$10. Cost of professional carburetor cleaning/rebuild: $50-$150.
Recoil Starter: The recoil starter mechanism can fail, preventing you from pulling the starter cord. Inspect the rope for fraying or damage. Make sure the pawls engage properly with the flywheel. If the recoil starter is damaged, it may need to be replaced. Cost of a new recoil starter assembly: $20-$40.

2. Chainsaw Runs Rough or Stalls

If the chainsaw starts but runs poorly, sputters, or stalls frequently, here are some things to check:

Fuel Mixture: Double-check that you’re using the correct fuel mixture. Too much oil can cause the saw to run rough and produce excessive smoke. Too little oil can damage the engine. The cost of engine damage from improper fuel mixture can easily exceed $200, even for a basic repair.
Carburetor Adjustment: The carburetor has adjustment screws that control the fuel-air mixture. If the carburetor is not properly adjusted, the saw may run rough or stall. The MS290 typically has three adjustment screws: “L” (low speed), “H” (high speed), and “LA” (idle speed). Refer to your owner’s manual for the proper adjustment procedure. Improper carburetor adjustment can lead to increased fuel consumption (up to 20%) and reduced engine life.
Spark Arrestor Screen: The spark arrestor screen is a small screen in the muffler that prevents sparks from escaping. If the screen becomes clogged with carbon buildup, it can restrict exhaust flow and cause the saw to run poorly. Remove the spark arrestor screen and clean it with a wire brush. Failure to clean the spark arrestor screen can reduce engine power by as much as 10%.
Fuel Line and Filter: Check the fuel line for cracks or leaks. Replace the fuel line if necessary. Also, check the fuel filter in the fuel tank. A clogged fuel filter can restrict fuel flow and cause the saw to stall. Replace the fuel filter if it’s dirty. Cost of a new fuel line and filter: $10-$20.

3. Chain Not Oiling Properly

Proper chain lubrication is essential for the life of the chain and bar. If the chain is not being oiled properly, it will overheat, wear out quickly, and can even break.

Oil Reservoir: Make sure the oil reservoir is full. Use bar and chain oil specifically designed for chainsaws. Using the wrong type of oil can damage the oil pump and reduce chain life.
Oil Filter: Check the oil filter in the oil reservoir. A clogged oil filter can restrict oil flow. Clean or replace the oil filter if it’s dirty. Cost of a new oil filter: $5-$10.
Oil Pump: The oil pump is responsible for pumping oil to the chain. If the oil pump is not working properly, the chain will not be lubricated. Check the oil pump for damage or wear. If the oil pump is faulty, it may need to be replaced. Cost of a new oil pump: $20-$50. Labor cost for replacement can range from $50-$100 at a repair shop.
Bar Oil Hole: The bar has a small oil hole that allows oil to flow to the chain. Make sure this hole is not clogged with debris. Clean the hole with a small wire or paperclip. A clogged oil hole can reduce chain life by as much as 50%.

4. Excessive Vibration

Excessive vibration can be a sign of a serious problem. It can also be very uncomfortable and tiring to use a chainsaw that vibrates excessively.

Chain Sharpness: A dull chain can cause excessive vibration. Sharpen the chain regularly. The cost of sharpening a chain at a shop typically ranges from $10-$20. Learning to sharpen your own chains can save you significant money in the long run.
Bar Condition: A bent or damaged bar can also cause vibration. Inspect the bar for damage. If the bar is bent, it may need to be replaced. Cost of a new bar: $30-$60.
Anti-Vibration Mounts: The MS290 has anti-vibration mounts that help to isolate the engine from the handles. If these mounts are damaged or worn, they can cause excessive vibration. Inspect the anti-vibration mounts for damage. Replace them if necessary. Cost of anti-vibration mounts: $10-$20 per set.
Loose Components: Check for any loose components, such as the muffler, carburetor, or cylinder head. Tighten any loose bolts or screws. Ignoring loose components can lead to more serious damage and costly repairs.

5. Chain Binds or Jams

A chain that binds or jams is not only frustrating but also dangerous.

Chain Tension: Make sure the chain is properly tensioned. The chain should be snug against the bar but should still be able to be pulled around the bar by hand. Improper chain tension can lead to premature wear of the chain and bar.
Bar Groove: The bar groove can become clogged with sawdust and debris, causing the chain to bind. Clean the bar groove regularly with a bar groove cleaner or a screwdriver. Neglecting the bar groove can reduce chain speed and increase the risk of kickback.
Drive Sprocket: The drive sprocket is the part that drives the chain. If the drive sprocket is worn, it can cause the chain to bind. Inspect the drive sprocket for wear. Replace it if necessary. Cost of a new drive sprocket: $15-$30.
Chain Condition: A damaged or worn chain can also cause binding. Inspect the chain for damage. If the chain is damaged, it needs to be replaced. Cost of a new chain: $20-$40.

The Hidden Costs of Firewood: Beyond the Chainsaw

Now, let’s talk about the bigger picture: the true cost of firewood. It’s not just the price of the chainsaw or the fuel you put in it. It’s a complex equation that includes everything from your time to the wear and tear on your equipment.

1. Timber Acquisition Costs

Standing Timber: If you’re harvesting your own timber, you need to factor in the cost of acquiring the rights to do so. This could involve purchasing timber rights from a landowner or obtaining a permit from a government agency. Timber prices vary widely depending on location, species, and quality. As of 2024, prices for standing timber can range from $20 to $100 per cord.
Purchased Logs: If you’re buying logs, the price will depend on the species, size, and quality of the logs. As of 2024, prices for delivered logs can range from $50 to $200 per cord. Factors like species, ease of splitting, and burning efficiency all influence the price. For example, oak and hickory command higher prices than pine or poplar.
Permits and Regulations: Don’t forget about permits. Depending on your location, you may need permits to harvest timber or transport logs. Permit fees can range from a few dollars to several hundred dollars. Ignorance of these regulations can lead to hefty fines.

2. Equipment Costs: Chainsaw, Splitter, and More

Chainsaw: We’ve already talked about chainsaw maintenance, but let’s consider the initial cost. A new Stihl MS290 typically costs around $500-$600.
