How to Start a Poulan Chainsaw (5 Pro Tips for Hard Starts)

The crisp autumn air bit at my cheeks as I tugged, once again, on the starter cord of my trusty Poulan chainsaw. Nothing. Just the dull thud of the engine refusing to ignite. A familiar frustration washed over me. I’d been there before, countless times, standing in the middle of the woods, surrounded by downed trees, and a chainsaw that stubbornly refused to cooperate. You know the feeling, right? The sinking sensation that your afternoon of productive work is about to turn into an extended wrestling match with a temperamental machine.

Over the years, I’ve learned that a hard-starting Poulan chainsaw isn’t necessarily a sign of impending doom. More often than not, it’s a matter of understanding its quirks and knowing the right techniques to coax it back to life. Through countless hours of trial and error, and a fair amount of colorful language directed at inanimate objects, I’ve developed a set of pro tips that have significantly reduced my chainsaw-induced headaches.

In this article, I’m going to share those tips with you. We’ll dive deep into the common causes of hard starts in Poulan chainsaws and, more importantly, the solutions that actually work. From fuel issues to spark plug problems, we’ll cover it all. So, grab a cup of coffee, settle in, and let’s get your Poulan chainsaw roaring to life.

Key Takeaways:

• Fresh Fuel is King: Stale fuel is the most common culprit behind hard starts. We’ll explore why and how to avoid it.
• Spark Plug Sanity Check: A fouled or damaged spark plug can prevent ignition. Learn how to inspect and clean (or replace) it.
• Carburetor Care is Crucial: The carburetor mixes fuel and air. We’ll look at basic carburetor adjustments and cleaning techniques.
• Air Filter Awareness: A clogged air filter restricts airflow, impacting engine performance and starting. Discover how to maintain it.
• Priming Power: Proper priming is essential for cold starts. This isn’t necessarily a design flaw, but rather a characteristic of smaller, two-stroke engines. Here’s a breakdown of the common factors that contribute to hard starts:
  • Two-Stroke Engine Complexity: Unlike four-stroke engines, two-stroke engines rely on a carefully balanced mixture of fuel and air to function properly. Any disruption to this balance can lead to starting problems.
  • Fuel Sensitivity: Two-stroke engines are particularly sensitive to fuel quality. Stale fuel, or fuel that has been improperly mixed with oil, can quickly gum up the carburetor and fuel lines.
  • Carburetor Design: The carburetors on Poulan chainsaws are relatively simple, which makes them affordable but also more susceptible to clogging and requiring adjustment.
  • Cold Start Challenges: Cold weather can exacerbate starting problems, as the fuel mixture becomes less volatile and harder to ignite.

  Pro Tip #1: Fresh Fuel is Your Best Friend

  I cannot stress this enough: stale fuel is the enemy of a smooth-starting chainsaw. I’ve seen so many people struggle with their chainsaws, only to discover that the fuel in the tank was months old.

  The Science Behind Stale Fuel:

  Gasoline, especially when mixed with two-stroke oil, degrades over time. The volatile components evaporate, leaving behind a gummy residue that can clog the carburetor jets and fuel lines. This process is accelerated by exposure to air and sunlight.

  Data Point: Studies have shown that gasoline can begin to degrade in as little as 30 days, with significant performance losses occurring after 90 days.

  My Personal Experience:

  I once spent an entire afternoon trying to start a Poulan chainsaw that had been sitting in my shed for a few months. After exhausting all other troubleshooting steps, I finally decided to drain the fuel tank and replace it with fresh fuel. To my surprise, the chainsaw started on the very first pull! It was a humbling reminder of the importance of fresh fuel.

  Actionable Steps:

  1. Use Fresh Fuel: Always use fresh gasoline that is less than 30 days old. Purchase fuel in small quantities to avoid having it sit for extended periods.
  2. Stabilize Your Fuel: If you know you won’t be using your chainsaw for a while, add a fuel stabilizer to the gasoline. Fuel stabilizers prevent the fuel from degrading and can extend its shelf life by several months. I personally recommend STA-BIL Fuel Stabilizer
  3. Proper Mixing Ratio: Always use the correct fuel-to-oil mixing ratio as specified in your Poulan chainsaw’s owner’s manual. Using the wrong ratio can lead to engine damage and starting problems. Most Poulan chainsaws require a 40:1 ratio (40 parts gasoline to 1 part two-stroke oil).
  4. Empty the Tank: If you’re storing your chainsaw for an extended period (e.g., over the winter), drain the fuel tank completely. This will prevent the fuel from gumming up the carburetor and fuel lines.
  5. Ethanol-Free Fuel: If possible, use ethanol-free gasoline. Ethanol can absorb water, which can lead to corrosion and starting problems, especially in older chainsaws. While it’s more expensive, it’s a worthwhile investment for the longevity of your equipment.

  Unique Insight: I’ve found that storing fuel in a sealed, opaque container in a cool, dark place can further extend its shelf life.

  Pro Tip #2: Spark Plug Sanity Check: The Heart of Ignition

  The spark plug is responsible for igniting the fuel-air mixture in the engine. A fouled, damaged, or improperly gapped spark plug can prevent ignition and cause hard starts.

  Understanding Spark Plug Function:

  The spark plug creates a high-voltage spark that jumps across a small gap between the electrode and the ground. This spark ignites the fuel-air mixture, initiating the combustion process.

  Common Spark Plug Problems:

  • Fouling: Carbon deposits can build up on the spark plug electrode, preventing it from firing properly. This is often caused by running the engine on a rich fuel mixture (too much fuel, not enough air).
  • Damage: The spark plug can be physically damaged by impact or overheating. Cracks in the ceramic insulator or a bent electrode can prevent it from functioning correctly.
  • Improper Gap: The gap between the electrode and the ground must be within the specified range for the spark plug to fire properly. An incorrect gap can result in a weak spark or no spark at all.

  Data Point: A fouled or damaged spark plug can reduce engine power by as much as 10-15%.

  My Personal Experience:

  I once spent hours trying to start a Poulan chainsaw, convinced that the problem was a clogged carburetor. After disassembling and cleaning the carburetor multiple times, I finally decided to check the spark plug. To my surprise, the electrode was completely covered in carbon deposits. After cleaning the spark plug, the chainsaw started immediately.

  Actionable Steps:

  1. Locate the Spark Plug: The spark plug is typically located on the side of the engine, near the cylinder head. Consult your owner’s manual for the exact location.
  2. Remove the Spark Plug: Use a spark plug wrench to remove the spark plug. Be careful not to damage the ceramic insulator.
  3. Inspect the Spark Plug: Examine the spark plug for signs of fouling, damage, or wear. Look for carbon deposits, cracks, or a bent electrode.
  4. Clean the Spark Plug: If the spark plug is fouled, clean it with a wire brush or spark plug cleaner. You can also use a small amount of carburetor cleaner to dissolve carbon deposits.
  5. Gap the Spark Plug: Use a spark plug gapping tool to ensure that the gap between the electrode and the ground is within the specified range (typically 0.025-0.030 inches). Consult your owner’s manual for the correct gap setting.
  6. Replace the Spark Plug: If the spark plug is damaged or worn, replace it with a new one of the same type. Refer to your owner’s manual for the correct spark plug part number.
  7. Reinstall the Spark Plug: Carefully reinstall the spark plug, tightening it to the specified torque (typically 15-20 ft-lbs). Be careful not to overtighten the spark plug, as this can damage the cylinder head.

  Unique Insight: I’ve found that using a small amount of anti-seize compound on the spark plug threads can make it easier to remove in the future.

  Pro Tip #3: Carburetor Care is Crucial: The Fuel-Air Mixer

  The carburetor is responsible for mixing fuel and air in the correct proportions for combustion. A clogged or improperly adjusted carburetor can cause hard starts, poor performance, and even engine damage.

  Understanding Carburetor Function:

  The carburetor uses a series of jets and passages to meter the flow of fuel and air. The fuel is drawn into the carburetor by the vacuum created by the engine’s intake stroke. The air is drawn in through the air filter and mixed with the fuel in the carburetor’s venturi.

  Common Carburetor Problems:

  • Clogging: The small jets and passages in the carburetor can become clogged with dirt, debris, or fuel residue. This can restrict the flow of fuel and air, leading to starting problems and poor performance.
  • Adjustment Issues: The carburetor has several adjustment screws that control the fuel-air mixture. If these screws are not properly adjusted, the engine may run too rich (too much fuel) or too lean (not enough fuel).
  • Diaphragm Problems: The carburetor’s diaphragm is a flexible membrane that helps to regulate the flow of fuel. Over time, the diaphragm can become stiff or cracked, leading to starting problems and poor performance.

  Data Point: A clogged carburetor can reduce engine power by as much as 20-30%.

  My Personal Experience:

  I once had a Poulan chainsaw that would start and run for a few minutes, then stall out. I tried everything I could think of, but nothing seemed to work. Finally, I decided to disassemble and clean the carburetor. To my surprise, the main jet was completely clogged with a small piece of debris. After cleaning the jet, the chainsaw ran like new.

  Actionable Steps:

  1. Locate the Carburetor: The carburetor is typically located on the side of the engine, between the air filter and the cylinder head. Consult your owner’s manual for the exact location.
  2. Inspect the Carburetor: Examine the carburetor for signs of dirt, debris, or fuel leaks.
  3. Clean the Carburetor: If the carburetor is dirty, clean it with carburetor cleaner. You can use a spray can of carburetor cleaner to flush out the jets and passages. For more thorough cleaning, you can disassemble the carburetor and soak the parts in carburetor cleaner.
  4. Adjust the Carburetor: The carburetor has two or three adjustment screws that control the fuel-air mixture. These screws are typically labeled “H” (high-speed), “L” (low-speed), and “T” (idle speed). To adjust the carburetor, start by turning both the “H” and “L” screws all the way in, then back them out 1-1/2 turns. Start the engine and let it warm up. Adjust the “L” screw until the engine idles smoothly. Adjust the “H” screw until the engine runs smoothly at full throttle. Adjust the “T” screw until the chain stops moving at idle.
  5. Replace the Carburetor: If the carburetor is severely damaged or cannot be properly adjusted, replace it with a new one of the same type.

  Unique Insight: I’ve found that using a small guitar string or a piece of fine wire can be helpful for cleaning out clogged carburetor jets. Be careful not to damage the jets.

  Pro Tip #4: Air Filter Awareness: Let Your Engine Breathe

  The air filter prevents dirt and debris from entering the engine. A clogged air filter restricts airflow, which can lead to hard starts, poor performance, and engine damage.

  Understanding Air Filter Function:

  The air filter is typically made of foam or paper. It is designed to trap dirt and debris before they can enter the engine.

  Common Air Filter Problems:

  • Clogging: The air filter can become clogged with dirt, dust, and debris over time. This restricts airflow and can cause the engine to run rich (too much fuel, not enough air).
  • Damage: The air filter can be physically damaged by impact or exposure to chemicals. A torn or damaged air filter will not effectively filter the air.

  Data Point: A clogged air filter can reduce engine power by as much as 10-15%.

  My Personal Experience:

  I once had a Poulan chainsaw that was running poorly and was difficult to start. I checked the fuel, spark plug, and carburetor, but everything seemed to be in order. Finally, I decided to check the air filter. To my surprise, the air filter was completely clogged with sawdust and dirt. After cleaning the air filter, the chainsaw ran much better.

  Actionable Steps:

  1. Locate the Air Filter: The air filter is typically located on top of the engine, under a plastic cover. Consult your owner’s manual for the exact location.
  2. Remove the Air Filter: Remove the air filter cover and take out the air filter.
  3. Inspect the Air Filter: Examine the air filter for signs of dirt, dust, or damage.
  4. Clean the Air Filter: If the air filter is made of foam, wash it with warm soapy water. Rinse the air filter thoroughly and allow it to dry completely. If the air filter is made of paper, tap it gently to remove loose dirt and dust. You can also use compressed air to blow out the dirt.
  5. Replace the Air Filter: If the air filter is damaged or cannot be properly cleaned, replace it with a new one of the same type.
  6. Reinstall the Air Filter: Reinstall the air filter and the air filter cover.

  Unique Insight: I’ve found that lightly oiling a foam air filter after cleaning it can help to trap more dirt and debris. Use a special air filter oil, as regular motor oil can clog the filter.

  Pro Tip #5: Priming Power: The Key to Cold Starts

  Priming the carburetor introduces fuel directly into the engine cylinder, making it easier to start, especially in cold weather.

  Understanding Priming Function:

  The primer bulb is a small rubber bulb that is located on the side of the carburetor. When you press the primer bulb, it draws fuel from the fuel tank and pumps it into the carburetor. This helps to prime the engine and make it easier to start.

  Common Priming Problems:

  • Incorrect Priming Procedure: Many people prime their chainsaws incorrectly, which can lead to flooding the engine.
  • Faulty Primer Bulb: The primer bulb can become cracked or damaged over time, preventing it from drawing fuel properly.
  • Clogged Primer Lines: The primer lines can become clogged with dirt or fuel residue, preventing fuel from reaching the carburetor.

  My Personal Experience:

  I used to struggle with starting my Poulan chainsaw in cold weather. I would prime it repeatedly, but it would still refuse to start. Finally, I learned the correct priming procedure from a more experienced logger. He told me to only prime the chainsaw a few times, until I could see fuel flowing through the primer lines. This simple tip made a huge difference in my chainsaw’s starting performance.

  Actionable Steps:

  1. Locate the Primer Bulb: The primer bulb is typically located on the side of the carburetor. Consult your owner’s manual for the exact location.
  2. Prime the Engine: Press the primer bulb several times until you can see fuel flowing through the primer lines. Do not over-prime the engine, as this can flood it. Usually 3-5 pumps is adequate.
  3. Start the Engine: Set the choke lever to the “full choke” position. Pull the starter cord until the engine starts.
  4. Adjust the Choke: Once the engine starts, gradually open the choke until the engine runs smoothly.

  Unique Insight: If you flood the engine, remove the spark plug and pull the starter cord several times to clear the excess fuel. Then, reinstall the spark plug and try starting the engine again.

  Additional Tips and Considerations

  Beyond the core tips outlined above, here are a few additional points to keep in mind when troubleshooting hard starts on your Poulan chainsaw:

  • Check the Fuel Lines: Inspect the fuel lines for cracks, leaks, or kinks. Replace any damaged fuel lines.
  • Inspect the Fuel Filter: The fuel filter is located inside the fuel tank. Check the fuel filter for clogs and clean or replace it as needed.
  • Check the Muffler: A clogged muffler can restrict exhaust flow and cause starting problems. Remove the muffler and inspect it for carbon buildup. Clean the muffler with a wire brush or carburetor cleaner.
  • Check the Starter Mechanism: Inspect the starter cord, recoil spring, and pawls for damage or wear. Replace any worn or damaged parts.
  • Compression Test: If you’ve tried all of the above steps and your chainsaw still won’t start, it’s possible that the engine has low compression. A compression test can help you determine if the engine needs to be rebuilt.
