Let’s talk about future-proofing your firewood game. Starting a Stihl MS290 chainsaw isn’t just about yanking a cord; it’s about mastering a skill that will serve you for years. I’ve spent countless hours in the woods, relying on my MS290 to get the job done. Over time, I’ve learned the nuances of this saw, the little tricks that make starting it a breeze, even on the coldest mornings. This guide is packed with those insights, turning you from a frustrated puller into a confident operator.

Starting a Stihl Chainsaw MS290: Pro Tips for Easy Ignition

The Stihl MS290 is a workhorse. I’ve seen it take down everything from small saplings to sizable oak trees. But like any machine, it has its quirks. Mastering the starting procedure is key to maximizing its lifespan and minimizing your frustration. This guide will walk you through every step, from pre-start checks to troubleshooting common issues.

Pre-Start Checks: Setting the Stage for Success

Before you even think about pulling that cord, a few crucial checks will save you time and potential headaches. Think of it as warming up before a workout – essential for preventing injury and maximizing performance.

Fuel and Oil Levels: The Lifeblood of Your Saw

Fuel: The MS290, like most two-stroke engines, requires a precise mix of gasoline and two-stroke oil. Stihl recommends a 50:1 ratio. I personally use Stihl Ultra HP two-stroke oil because of its low smoke and superior engine protection. Always use fresh, high-octane gasoline (at least 89 octane). Old fuel can gum up the carburetor and make starting a nightmare. I’ve learned this the hard way after leaving fuel in the saw over the winter. Now, I always drain the tank or use a fuel stabilizer.
- Measurement: A 50:1 ratio translates to 2.6 fluid ounces of oil per gallon of gasoline.
Chain Oil: The chain oil keeps the chain lubricated, reducing friction and preventing premature wear. I prefer using a high-quality bar and chain oil like Stihl Bar & Chain Lubricant. Check the oil level before each use and top it off as needed. Running the saw with low chain oil will quickly ruin the bar and chain.
- Visual Check: The oil tank should be visibly full. Monitor consumption during use; a properly lubricated chain will fling a fine mist of oil.

Chain and Bar Inspection: Safety First

Chain Sharpness: A dull chain is not only inefficient but also dangerous. It requires more force to cut, increasing the risk of kickback. I sharpen my chains regularly using a Stihl 2-in-1 Easy File. A sharp chain will pull itself into the wood with minimal pressure.
- Rule of Thumb: If you have to force the saw, the chain is likely dull.
Chain Tension: The chain should be snug on the bar but still able to be pulled around by hand. Too loose, and it can derail; too tight, and it will bind and overheat. Adjust the tension using the screw on the side of the saw.
- Proper Tension: When you pull the chain away from the bar at the midpoint, you should see about 1/8 inch of daylight.
Bar Condition: Inspect the bar for wear, damage, and proper lubrication. Clean the bar groove regularly with a screwdriver or bar groove cleaner. A damaged bar can cause the chain to derail or break.
- Maintenance Tip: Flip the bar periodically to ensure even wear.

Safety Features: Your Protective Shield

Chain Brake: This is your primary safety device. Ensure it engages properly by pushing it forward. The chain should stop immediately. I always test the chain brake before each use.
Throttle Lockout: This prevents accidental throttle engagement. Make sure it functions correctly, requiring you to depress it before squeezing the throttle.
Kill Switch: Familiarize yourself with the location and function of the kill switch. In an emergency, this is your lifeline.

Takeaway: Diligence in these pre-start checks sets the stage for a safe and efficient cutting session. Don’t skip them!

The Starting Procedure: A Step-by-Step Guide

Now, let’s get down to the nitty-gritty of starting your MS290. Follow these steps carefully, and you’ll be cutting wood in no time.

Step 1: Engage the Chain Brake

Always engage the chain brake before starting the saw. This prevents the chain from moving during the starting process, significantly reducing the risk of injury.

Step 2: Master the Starting Positions: Cold vs. Warm Start

The MS290 has two starting positions, depending on whether the engine is cold or warm. Understanding the difference is crucial for successful starting.

Cold Start: When the engine is cold (hasn’t been run recently), you’ll need to use the choke to enrich the fuel mixture.
- Choke Lever Position: Move the choke lever all the way down (fully closed). This restricts airflow, allowing more fuel to enter the cylinder.
Warm Start: If the engine is warm (has been running recently), you typically don’t need to use the choke.
- Choke Lever Position: Leave the choke lever in the “run” position (fully open).

Step 3: Priming the Carburetor (If Needed)

Some MS290 models have a primer bulb. If yours does, press it several times until you see fuel entering the bulb. This helps draw fuel into the carburetor, making starting easier. I usually prime mine about 6-8 times when cold.

Step 4: The Starting Stance: Stability is Key

Place the saw on a firm, flat surface. I prefer to place my left foot through the rear handle, providing a secure anchor. Grip the front handle firmly with your left hand.

Step 5: The Pull Start: Technique Matters

Grip: Use your right hand to grip the starter handle firmly.
Pull: Pull the starter cord slowly until you feel resistance. This engages the starter mechanism. Then, give it a sharp, full pull. Avoid pulling the cord all the way out, as this can damage the starter.
Repeat: Repeat the pull until the engine sputters or attempts to start.

Step 6: Adjusting the Choke (Cold Start Only)

After the engine sputters (cold start only), move the choke lever to the half-choke position (middle position). This allows more air into the mixture. Continue pulling the starter cord until the engine starts and runs smoothly.

Step 7: Warming Up the Engine

Let the engine idle for a few minutes before using the saw. This allows the engine to reach operating temperature and ensures proper lubrication. I usually let mine warm up for about 2-3 minutes.

Step 8: Disengaging the Chain Brake

Once the engine is warmed up, disengage the chain brake by pulling it back towards you. Now you’re ready to cut!

Takeaway: Mastering the starting procedure involves understanding the choke positions, priming the carburetor, and using proper pulling technique. Practice makes perfect!

Troubleshooting Common Starting Problems: Diagnosing the Issues

Even with the best technique, you might encounter starting problems. Here are some common issues and their solutions.

Flooded Engine: Too Much Fuel

Symptoms: The engine won’t start, and you may smell fuel.
Solution: Remove the spark plug and pull the starter cord several times to clear excess fuel from the cylinder. Let the cylinder air out for a few minutes. Reinstall the spark plug and try starting the saw with the choke in the “run” position (fully open). I’ve had to do this more times than I care to admit, especially when experimenting with different fuel mixtures.

No Spark: Ignition Problems

Symptoms: The engine won’t start, and there’s no sign of combustion.
Solution: Check the spark plug for proper gap and cleanliness. The gap should be around 0.020 inches. Clean the spark plug with a wire brush or replace it if necessary. Also, check the spark plug wire and ignition coil for damage.
- Testing for Spark: Remove the spark plug, attach the spark plug wire, and ground the spark plug against the engine. Pull the starter cord. You should see a bright blue spark. If not, the ignition coil may be faulty.

Fuel Delivery Issues: A Starved Engine

Symptoms: The engine starts briefly but then dies, or it won’t start at all.
Solution: Check the fuel filter in the fuel tank. A clogged fuel filter can restrict fuel flow. Replace the fuel filter if necessary. Also, check the fuel lines for cracks or leaks.
- Fuel Line Inspection: Look for cracks or discoloration in the fuel lines. Replace any damaged lines.

Carburetor Problems: The Heart of the Engine

Symptoms: The engine runs poorly, idles erratically, or won’t start.
Solution: The carburetor may need cleaning or adjustment. Carburetors are complex, and I recommend taking it to a qualified technician if you’re not comfortable working on them. However, you can try cleaning the carburetor with carburetor cleaner.
- Carburetor Cleaning: Disassemble the carburetor carefully, noting the position of all parts. Spray all passages and components with carburetor cleaner. Reassemble the carburetor and adjust the idle speed screw.

Compression Issues: A Sign of Wear

Symptoms: The engine is difficult to pull over, or it has very little resistance.
Solution: Compression issues can indicate worn piston rings or a damaged cylinder. This is a more serious problem that may require engine rebuild or replacement. A compression test can confirm this diagnosis.
- Compression Test: A healthy MS290 should have a compression reading of at least 120 PSI.

Takeaway: Troubleshooting starting problems requires a systematic approach. Start with the simplest solutions and work your way up to more complex issues.

Fine-Tuning Your MS290: Optimizing Performance

Once you’ve mastered the starting procedure, you can fine-tune your MS290 for optimal performance.

Carburetor Adjustment: Balancing Fuel and Air

The MS290 has three adjustment screws on the carburetor:

L (Low-Speed): Adjusts the fuel mixture at idle and low speeds.
H (High-Speed): Adjusts the fuel mixture at high speeds.
LA (Idle Speed): Adjusts the idle speed.

Important: Carburetor adjustment should be done with the engine warmed up and running.

Idle Speed Adjustment: Turn the LA screw until the chain stops moving at idle. The engine should idle smoothly without stalling.
Low-Speed Adjustment: Turn the L screw until the engine accelerates smoothly from idle to full throttle.
High-Speed Adjustment: The H screw is best left to a qualified technician, as incorrect adjustment can damage the engine.

Chain Sharpening: Maintaining Cutting Efficiency

A sharp chain is essential for efficient and safe cutting. I sharpen my chains regularly using a Stihl 2-in-1 Easy File.

Filing Angle: The correct filing angle is typically marked on the chain.
Depth Gauge: Check the depth gauges (the small rakers in front of each cutting tooth) and file them down if necessary.
Consistency: File each tooth evenly to maintain a consistent cutting edge.

Air Filter Maintenance: Breathing Easy

A clean air filter is crucial for proper engine performance. Clean the air filter regularly with soap and water. Allow it to dry completely before reinstalling. I clean mine after every 5-10 hours of use.

Takeaway: Fine-tuning your MS290 involves carburetor adjustment, chain sharpening, and air filter maintenance. These simple steps can significantly improve performance and extend the life of your saw.
