Poulan Pro Wild Thing Chainsaw (5 Expert Tips for Revival)
Ever yanked on a chainsaw cord until your arm felt like it was going to fall off, only to be greeted by nothing more than a stubborn silence? I have. More times than I’d care to admit, and often with a Poulan Pro Wild Thing. It’s a common lament. Many a weekend warrior has felt the frustration of a temperamental Wild Thing, especially when you’re itching to get some wood cut. But don’t despair; these little powerhouses are often more resilient than they seem. They just need a little… coaxing.
That’s why I’ve compiled this guide: “Poulan Pro Wild Thing Chainsaw (5 Expert Tips for Revival).” I’m going to share five expert tips, drawn from years of personal experience and observation, that will breathe new life into your balky Wild Thing. These aren’t just quick fixes; they’re strategies for understanding your saw and keeping it running smoothly for years to come.
The Poulan Pro Wild Thing: A Love-Hate Relationship
The Poulan Pro Wild Thing. The name alone conjures images of untamed power, ready to tear through logs with wild abandon. And, when they’re running right, they do! They’re lightweight, relatively inexpensive, and surprisingly capable for their size. I remember my first Wild Thing. I bought it used at a flea market for next to nothing. It looked rough, but after a little TLC, it became my go-to saw for limbing and small firewood projects.
But here’s the rub: these saws can be… finicky. They can be hard to start, prone to stalling, and sometimes just plain stubborn. This is why so many end up gathering dust in garages or being relegated to the “parts saw” pile. The good news is that with a little know-how, you can turn that frustration into satisfaction.
Tip #1: Fuel is King (and Queen)
The Stale Fuel Fiasco
The number one culprit behind a non-starting or poorly running Poulan Pro Wild Thing is almost always fuel related. I can’t stress this enough: old fuel is the enemy. Gasoline degrades over time, especially when mixed with oil. This degradation leads to varnish buildup in the carburetor, clogged fuel lines, and a general inability for the engine to get the fuel it needs.
I’ve seen it countless times. A friend calls, exasperated that his saw won’t start. The first question I ask? “How old is the fuel?” Nine times out of ten, the answer is “a few months” or even “I’m not sure!” Fuel older than 30 days is suspect, and fuel older than 90 days is practically guaranteed to cause problems.
Data Point: Studies have shown that gasoline can lose up to 50% of its octane rating in just three months when stored improperly. This loss of octane can lead to hard starting, poor performance, and even engine damage.
Actionable Takeaway:
- Always use fresh fuel. Mix only what you need for a few weeks at most.
- Use a fuel stabilizer. Products like Sta-Bil or Sea Foam can significantly extend the life of your fuel. I personally use Sta-Bil in every can of mixed fuel I make.
- Empty the fuel tank before storing the saw for extended periods. Run the saw until it stalls to ensure the carburetor is also empty.
- Use the correct fuel mixture ratio. Poulan Pro Wild Thing chainsaws typically require a 40:1 fuel-to-oil ratio. Check your owner’s manual to be certain.
The Ethanol Enigma
Another fuel-related issue is the presence of ethanol in modern gasoline. Ethanol can absorb water, leading to phase separation (where the ethanol and water separate from the gasoline and oil) and corrosion of fuel system components. This is particularly problematic in small engines like chainsaws.
Data Point: Ethanol can cause rubber and plastic components in older fuel systems to degrade, leading to leaks and clogs.
Actionable Takeaway:
- Use ethanol-free fuel whenever possible. This is the best way to avoid ethanol-related problems. Look for “recreational fuel” or “marine fuel” at gas stations.
- If you must use fuel containing ethanol, use a fuel stabilizer specifically designed to combat its effects.
- Inspect your fuel lines and carburetor regularly for signs of degradation. Replace them if necessary.
My Own Fuel Fiasco
I once made the mistake of leaving a can of mixed fuel sitting in my shed for over a year. When I went to use it, the saw wouldn’t even sputter. I drained the old fuel, cleaned the fuel filter, and tried again. Still nothing. I ended up having to completely disassemble and clean the carburetor to get the saw running again. Lesson learned: fresh fuel is non-negotiable.
Tip #2: Spark, the Lifeblood of Combustion
The Spark Plug Examination
If your fuel is fresh and your saw still won’t start, the next place to look is the spark plug. A faulty spark plug can prevent the engine from firing, even if everything else is in perfect working order.
Actionable Takeaway:
- Remove the spark plug and inspect it. Look for cracks, carbon buildup, or excessive wear.
- Clean the spark plug with a wire brush. You can also use a spark plug cleaner.
- Check the spark plug gap. The correct gap for a Poulan Pro Wild Thing is typically around 0.025 inches. Use a spark plug gap tool to ensure the gap is correct.
- Test the spark plug. Attach the spark plug wire to the spark plug and ground the spark plug against the engine block. Pull the starter cord. You should see a strong, blue spark. If the spark is weak or nonexistent, replace the spark plug.
Data Point: A fouled or worn spark plug can reduce engine power by as much as 30%.
The Ignition Coil Conundrum
If you’ve replaced the spark plug and you’re still not getting a spark, the problem may be with the ignition coil. The ignition coil is responsible for generating the high-voltage spark that ignites the fuel-air mixture in the cylinder.
Actionable Takeaway:
- Check the ignition coil air gap. The air gap is the distance between the ignition coil and the flywheel. The correct air gap is crucial for proper spark generation. Consult your owner’s manual for the correct air gap specification.
- Test the ignition coil with a multimeter. This requires some electrical knowledge, but it’s the best way to determine if the ignition coil is functioning properly. If the ignition coil is faulty, replace it.
Spark Plug Story
I once spent an entire afternoon troubleshooting a Wild Thing that wouldn’t start. I checked the fuel, cleaned the carburetor, and even replaced the fuel lines. Nothing worked. Finally, as a last resort, I decided to replace the spark plug, even though it looked relatively clean. To my surprise, that did the trick! The old spark plug was producing a weak spark that wasn’t strong enough to ignite the fuel-air mixture.
Tip #3: Air Flow is Essential
The Air Filter Factor
A clogged air filter can restrict airflow to the engine, leading to poor performance and hard starting. The Poulan Pro Wild Thing, like many two-stroke engines, is particularly sensitive to air filter condition.
Actionable Takeaway:
- Remove the air filter and inspect it. Look for dirt, dust, and debris.
- Clean the air filter with soap and water. Allow the air filter to dry completely before reinstalling it.
- Replace the air filter if it is damaged or excessively dirty.
Data Point: A clogged air filter can reduce engine power by up to 15%.
The Intake Inspection
Beyond the air filter, make sure the entire intake system is clear. Check for obstructions in the air intake tube and around the carburetor.
Actionable Takeaway:
- Visually inspect the air intake tube for any blockages.
- Ensure the carburetor is securely mounted and there are no air leaks around the mounting flange.
Air Filter Anecdote
I was helping a friend cut firewood one day when his Wild Thing started running rough and losing power. We checked the fuel, the spark plug, and everything else we could think of. Finally, I decided to take a look at the air filter. It was completely clogged with sawdust. After cleaning the air filter, the saw ran like new again.
Tip #4: Carburetor Calamities and Cures
The Carburetor’s Crucial Role
The carburetor is responsible for mixing fuel and air in the correct proportions to create a combustible mixture. A dirty or malfunctioning carburetor is a common cause of starting and running problems.
Actionable Takeaway:
- Clean the carburetor. This is often the first step in troubleshooting carburetor problems. You can use carburetor cleaner to dissolve varnish and deposits.
- Rebuild the carburetor. If cleaning doesn’t solve the problem, you may need to rebuild the carburetor. This involves disassembling the carburetor, replacing worn parts, and reassembling it. Carburetor rebuild kits are readily available online.
- Adjust the carburetor settings. The carburetor has two or three adjustment screws that control the fuel-air mixture. The “L” screw controls the low-speed mixture, the “H” screw controls the high-speed mixture, and some carburetors have an “LA” screw that controls the idle speed. Consult your owner’s manual for the correct adjustment procedure.
Data Point: A properly tuned carburetor can improve fuel efficiency by up to 20%.
The Carburetor Cleaning Process
Cleaning a carburetor isn’t as daunting as it sounds. Here’s a simplified process:
- Remove the carburetor: Carefully disconnect the fuel lines and linkage.
- Disassemble the carburetor: Take photos as you go to remember how everything fits back together.
- Soak the parts: Soak the metal parts in carburetor cleaner for at least 30 minutes.
- Clean the jets: Use a small wire or carburetor cleaning tool to clean out the jets.
- Reassemble the carburetor: Replace any worn or damaged parts.
- Reinstall the carburetor: Reconnect the fuel lines and linkage.
My Carburetor Catastrophe (and Recovery)
I once tried to clean a carburetor without taking it apart. I sprayed carburetor cleaner into the intake and hoped for the best. Needless to say, it didn’t work. I ended up having to completely disassemble the carburetor anyway. I learned my lesson: there’s no substitute for a thorough cleaning.
Carburetor Adjustment – The Art of the Tune
Carburetor adjustment is a bit of an art, but here’s the general idea:
- Start with the factory settings: Consult your owner’s manual for the recommended settings.
- Adjust the low-speed screw (L): Turn the screw in (clockwise) until the engine starts to stumble, then turn it out (counterclockwise) until the engine runs smoothly at idle.
- Adjust the high-speed screw (H): Make a test cut. If the engine bogs down under load, turn the screw out slightly. If the engine runs rough or smokes excessively, turn the screw in slightly.
Important Note: Be careful not to overtighten the adjustment screws, as this can damage the carburetor.
Tip #5: The Importance of Maintenance
Regular Maintenance is Key
Preventive maintenance is the best way to keep your Poulan Pro Wild Thing running smoothly and avoid costly repairs. Regular maintenance includes:
- Cleaning the air filter regularly.
- Replacing the spark plug annually.
- Inspecting the fuel lines and fuel filter regularly.
- Sharpening the chain regularly.
- Lubricating the chain regularly.
- Checking the chain tension regularly.
- Storing the saw properly.
Data Point: Regular maintenance can extend the life of your chainsaw by up to 50%.
Chain Sharpening: A Sharp Chain is a Safe Chain
A dull chain not only cuts poorly, but it’s also more dangerous. A dull chain is more likely to kick back, which can cause serious injury.
Actionable Takeaway:
- Sharpen the chain regularly. You can use a file, a chain grinder, or a professional sharpening service.
- Maintain the correct depth gauge settings. The depth gauges are the small tabs in front of each cutter. If the depth gauges are too high, the chain will cut poorly. If the depth gauges are too low, the chain is more likely to kick back.
I’ve seen firsthand the difference a sharp chain makes. I was cutting some large oak logs with a dull chain, and the saw was struggling to get through the wood. I decided to sharpen the chain, and the difference was night and day. The saw cut through the oak like butter.
Lubrication: Keep Things Oiled
Proper chain lubrication is essential for extending the life of the chain and bar.
Actionable Takeaway:
- Use a high-quality bar and chain oil.
- Check the oil level regularly.
- Make sure the oiler is working properly.
Storage Strategies: Putting Your Saw to Bed
Proper storage is crucial for preventing problems when you go to use your saw again.
Actionable Takeaway:
- Drain the fuel tank.
- Run the saw until it stalls to empty the carburetor.
- Remove the spark plug and add a few drops of oil to the cylinder.
- Pull the starter cord a few times to distribute the oil.
- Clean the saw thoroughly.
- Store the saw in a dry place.
My Maintenance Mishap
I once neglected to drain the fuel from my Wild Thing before storing it for the winter. When I went to use it the following spring, the fuel had turned into a gummy mess that clogged the carburetor. I had to spend hours cleaning the carburetor before I could get the saw running again.
Beyond the Basics: Advanced Troubleshooting
If you’ve tried all of the above tips and your Poulan Pro Wild Thing is still giving you trouble, you may need to delve into some more advanced troubleshooting. This may involve:
- Checking the compression. Low compression can indicate worn piston rings or a damaged cylinder.
- Inspecting the fuel lines for leaks.
- Testing the fuel pump.
- Checking the impulse line. The impulse line connects the crankcase to the carburetor and provides the vacuum necessary to operate the fuel pump.
- Looking for air leaks around the crankshaft seals.
These are more involved procedures that may require specialized tools and knowledge. If you’re not comfortable performing these tasks yourself, it’s best to take your saw to a qualified repair technician.
Wood Species and Processing: A Brief Diversion
While we’re on the subject of chainsaws, let’s touch on the importance of understanding different wood species and their impact on processing. The type of wood you’re cutting can significantly affect the performance of your saw and the lifespan of your chain.
Data Point: Cutting hardwoods like oak and maple will dull your chain much faster than cutting softwoods like pine and fir.
Actionable Takeaway:
- Learn to identify different wood species.
- Adjust your cutting techniques based on the type of wood you’re cutting.
- Sharpen your chain more frequently when cutting hardwoods.
- Consider using a different type of chain for cutting hardwoods.
I’ve spent countless hours cutting various types of wood, from soft pine to dense hickory. I’ve learned that each species requires a different approach. Pine is relatively easy to cut, but it can be sappy and gum up your saw. Hickory is incredibly strong and durable, but it can be a real challenge to cut, even with a sharp chain.
Safety First: A Non-Negotiable
No discussion of chainsaws would be complete without emphasizing the importance of safety. Chainsaws are powerful tools that can cause serious injury if used improperly.
Actionable Takeaway:
- Always wear appropriate safety gear, including:
- Eye protection
- Hearing protection
- Gloves
- Chaps
- Steel-toed boots
- Read and understand the owner’s manual.
- Never operate a chainsaw when you are tired or under the influence of drugs or alcohol.
- Be aware of your surroundings.
- Use the correct cutting techniques.
- Maintain your chainsaw properly.
I’ve seen too many accidents involving chainsaws. It’s simply not worth the risk. Always prioritize safety.
