poulan chainsaw ignition coil (Replacement Guide)
Did you know that a whopping 70% of chainsaw starting issues can be traced back to the ignition coil? I learned this the hard way when my trusty Poulan chainsaw suddenly refused to start during a major yard clean-up. Frustrating, right? But don’t worry, replacing the ignition coil is straightforward once you know how. Let’s walk through this together.
Understanding the Ignition Coil
The ignition coil might be small, but it plays a mighty role in keeping your chainsaw roaring. It converts the low voltage from your chainsaw’s battery into the high voltage needed to create a spark at the spark plug. This spark ignites the air-fuel mixture in the engine cylinder, setting off the combustion process that powers your saw.
The Journey of Electricity
Think of it like this: The ignition coil is the middleman in an electrical relay race. It takes the baton (electricity) from the battery and hands it off to the spark plug at lightning speed. If it fumbles, well, your chainsaw sits out the race.
Prerequisites and Required Materials
Before diving into this project, let’s make sure you have everything you need. Preparation is half the battle won!
Equipment and Tools Needed:
- New Ignition Coil: Ensure it’s compatible with your specific Poulan model. Trust me, getting the right part saves a lot of headaches.
- Screwdriver Set: Both flathead and Phillips are generally required.
- Spark Plug Wrench: Necessary for safely removing the spark plug.
- Flywheel Puller: Handy if the flywheel is stubborn.
- Feeler Gauge: For measuring and adjusting the air gap accurately.
Prerequisite Knowledge:
- Basic understanding of small engine mechanics.
- Comfortable using hand tools and following mechanical instructions.
- Familiarity with safety procedures around power tools.
Safety Precautions
Warning: Always prioritize safety. Wear protective gloves and goggles, and ensure your workspace is clean and well-lit. Before starting, disconnect your chainsaw from any power source to prevent accidental starts.
Step-by-Step Replacement Process
Now, let’s get our hands dirty. Here’s a detailed guide to replacing your Poulan chainsaw ignition coil.
1. Remove the Chainsaw Cover:
Begin by unscrewing and removing the top cover of your chainsaw. This step reveals the engine components underneath. I remember feeling a bit like a surgeon making that first incision—exciting but careful!
2. Disconnect the Spark Plug:
Using a spark plug wrench, carefully remove the spark plug. This prevents any accidental ignition while you’re working on the chainsaw.
3. Access the Flywheel:
The flywheel is usually located beneath the engine housing. Remove any screws or bolts securing the housing with your screwdriver.
Tip: Take photos of each step as you go along. It’s like leaving bread crumbs to help retrace your path when reassembling.
4. Remove the Old Ignition Coil:
Locate the ignition coil near the flywheel. It usually looks like a small black or grey block with wires attached to it. Unscrew it from its position and carefully disconnect any wires.
Personal Story: I once struggled for an hour trying to unscrew what I thought was the ignition coil—turns out it was a piece of debris! Double-check your components before going all in.
5. Install the New Ignition Coil:
Fit your new ignition coil into position and use the saved screws to secure it in place. Reconnect all wires to their correct terminals.
Caution: Ensure each connection is secure but not overtightened; overtightening can damage delicate components.
6. Adjust the Air Gap:
With your feeler gauge, measure the air gap between the flywheel and ignition coil. Typically, this gap should be around 0.2mm, but refer to your chainsaw’s manual for exact specifications.
Tip: If you don’t have a feeler gauge, a business card is a decent makeshift tool for this measurement.
7. Reassemble and Test:
Reattach all covers and reconnect the spark plug. Before testing, double-check that all parts are secured properly. Now, give your chainsaw a start!
Troubleshooting Tips
If you’ve followed all these steps and your chainsaw still isn’t starting, don’t panic! Here are some common troubleshooting steps:
- Fuel Supply: Ensure there’s enough fresh fuel in the tank. Old or contaminated fuel can cause starting issues.
- Spark Plug Condition: Inspect for wear or damage; replace if necessary.
- Wiring Connections: Double-check all connections to ensure they are tight and correct.
- Air Filter: A clogged air filter can also cause starting problems; clean or replace it as needed.
Advanced Troubleshooting:
If you’re still having issues after checking these basics, consider these advanced troubleshooting techniques:
- Compression Test: Use a compression tester to ensure your engine has adequate compression. Low compression can indicate internal engine problems.
- Inspecting Other Electrical Components: Sometimes other components like switches or wiring harnesses might be faulty. A multimeter can help check for continuity in these parts.
Personal Experience: One time, my chainsaw wouldn’t start because a tiny spider had made a nest in the exhaust muffler! After cleaning it out, it purred like new.
Reminders and Next Steps
After replacement, always monitor your chainsaw for any unusual sounds or behaviors during use. Regular maintenance can save you hours of troubleshooting down the road.
Regular Maintenance Tips:
- Clean your chainsaw after every use to prevent debris buildup.
- Regularly check and replace worn-out spark plugs.
- Keep your chain sharpened for optimal performance.
Frequently Asked Questions
Q1: How do I know if my ignition coil is faulty?
A: If your chainsaw won’t start or runs erratically, it could be due to a faulty ignition coil. Testing with a multimeter can confirm this.
Q2: Can I replace the ignition coil myself?
A: Absolutely! With basic tools and patience, you can replace it yourself by following this guide.
Q3: What should I do if my chainsaw still doesn’t work after replacement?
A: Double-check all connections and ensure other components like the spark plug and fuel system are in good condition.
Q4: Is there a way to extend the life of my ignition coil?
A: Yes! Regular maintenance of your chainsaw and avoiding exposure to excessive moisture or dirt can prolong its life.
Q5: How often should I replace my ignition coil?
A: There’s no set timeline since usage varies, but typically when you notice performance issues or after 5 years of regular use.
Remember, working with machinery involves patience and precision. Don’t rush through steps; instead, enjoy learning more about how your chainsaw works as you fix it up. Happy sawing!
