9. Prime the System: Press the primer bulb several times until it fills with fuel.
10. Reconnect the Spark Plug Wire: Reconnect the spark plug wire and attempt to start the saw.

Unique Insight: When cleaning a carburetor, pay close attention to the idle adjustment screw and the high-speed adjustment screw. These screws control the fuel mixture and can significantly impact the saw’s performance. Refer to your owner’s manual for the correct settings.

Case Study: I once worked with a community forestry group that had several Poulan Wild Thing chainsaws that were used for trail maintenance. The saws were constantly stalling and lacked power. After cleaning the carburetors and adjusting the fuel mixture, the saws ran like new, allowing the group to complete their work much more efficiently. This highlights the importance of proper carburetor maintenance for optimal chainsaw performance.

2. Spark Ignition: Igniting the Fire Within

If the fuel system is working correctly, the next step is to check the spark ignition system. This system is responsible for generating the spark that ignites the air-fuel mixture in the cylinder.

Diagnosing the Problem

Here are some common signs of spark ignition problems:

• No Spark: The saw refuses to start and there is no spark at the spark plug.
• Weak Spark: The saw starts but runs poorly, with a weak or intermittent spark.
• Difficult Starting: The saw is difficult to start, especially in cold weather.

The Expert Fix: Spark Plug Inspection and Replacement

The spark plug is the most common point of failure in the ignition system. Over time, the spark plug can become fouled with carbon deposits, or the electrode gap can widen, reducing the spark’s effectiveness.

6. Reconnect the Ignition Coil Wires: Reconnect the wires to the ignition coil.
7. Reconnect the Spark Plug Wire: Reconnect the spark plug wire and attempt to start the saw.

Unique Insight: When testing the ignition coil, make sure the multimeter is set to the correct resistance range. Also, ensure that the multimeter probes are making good contact with the ignition coil terminals.

3. Compression: The Squeeze That Matters

Compression is the measure of how tightly the air-fuel mixture is compressed in the cylinder. Low compression can make the saw difficult to start and reduce its power output.

Diagnosing the Problem

Here are some signs of low compression:

• Hard Starting: The saw requires excessive pulling to start.
• Lack of Power: The saw struggles to cut, even in soft wood.
• Engine Sounds Weak: The engine sounds weak or “soft” when pulled over.

The Expert Fix: Compression Testing

The best way to check the compression is to use a compression tester.

What you’ll need:

• Compression tester
• Spark plug wrench
• Screwdriver

The Process:

1. Safety First: Disconnect the spark plug wire.
2. Remove the Spark Plug: Use the spark plug wrench to remove the spark plug from the cylinder head.
3. Install the Compression Tester: Install the compression tester into the spark plug hole.
4. Pull the Starter Cord: Pull the starter cord several times until the compression tester reading stabilizes.
5. Read the Compression: Read the compression tester gauge. A healthy Poulan Wild Thing should have a compression reading of at least 100 PSI.
6. Interpret the Results: If the compression reading is below 100 PSI, the engine likely has low compression.

Data Point: A compression reading below 90 PSI typically indicates significant engine wear and the need for major repairs.

The Expert Fix: Addressing Low Compression

If the compression is low, there are several possible causes:

• Worn Piston Rings: The piston rings seal the gap between the piston and the cylinder wall. Over time, the rings can wear down, allowing air and fuel to leak past, resulting in low compression.
• Damaged Cylinder: The cylinder wall can become scratched or damaged, which can also lead to low compression.
• Leaking Gaskets: The cylinder head gasket or the base gasket can leak, allowing air and fuel to escape, resulting in low compression.

Addressing these issues typically requires a more in-depth repair, which may involve:

• Replacing the Piston Rings: This involves removing the cylinder and piston, replacing the worn rings, and reassembling the engine.
• Replacing the Cylinder: If the cylinder is damaged, it may need to be replaced.
• Replacing Gaskets: Replacing the cylinder head gasket or base gasket can restore compression if the leak is due to a faulty gasket.

Unique Insight: Before assuming the worst, try adding a small amount of oil to the cylinder through the spark plug hole and retesting the compression. If the compression reading increases significantly, it indicates that the piston rings are likely the primary cause of the low compression. This is a quick way to differentiate between piston ring issues and cylinder damage.

4. Sharpening the Chain: The Cutting Edge

A dull chain is a major cause of poor cutting performance and increased strain on the engine. A sharp chain, on the other hand, cuts quickly and efficiently, reducing the risk of kickback and prolonging the life of the saw.

Diagnosing the Problem

Here are some signs that your chainsaw chain needs sharpening:

• Sawdust Instead of Chips: A sharp chain produces long, thin chips of wood. A dull chain produces fine sawdust.
• Difficulty Cutting: The saw requires excessive force to cut, and the chain tends to skip or bounce.
• Crooked Cuts: The saw cuts unevenly, producing crooked or angled cuts.
• Excessive Vibration: A dull chain can cause excessive vibration, making the saw uncomfortable to use.
• Smoke: Excessive friction from a dull chain can cause the wood to smoke.

The Expert Fix: Chain Sharpening Techniques

There are several ways to sharpen a chainsaw chain:

• Hand Filing: This is the most common method, and it involves using a round file and a flat file to sharpen each cutter.
• Electric Chain Sharpener: This is a faster and more precise method, but it requires a dedicated electric sharpener.
• Professional Sharpening: You can also take your chain to a professional sharpening service.

What you’ll need for hand filing:

• Flat file
• File guide
• Depth gauge tool
• Gloves
• Vise

The Process (Hand Filing):

1. Secure the Chain: Secure the chain in a vise.
2. File the Cutters: Using the round file and file guide, sharpen each cutter to the correct angle and depth. Refer to your owner’s manual for the correct filing angles.
3. File the Depth Gauges: Using the flat file and depth gauge tool, file the depth gauges to the correct height.
4. Rotate the Chain: Rotate the chain and repeat the process for each cutter.
5. Inspect the Chain: Inspect the chain for any damaged or worn cutters.

Data Point: A properly sharpened chain can increase cutting speed by up to 50% and reduce fuel consumption by up to 20%.

Unique Insight: When hand filing, it’s crucial to maintain the correct filing angles. Using a file guide can help ensure consistent and accurate sharpening. Also, remember to file the depth gauges after sharpening the cutters. The depth gauges control the amount of wood each cutter can remove, and if they are too high, the chain will not cut effectively.

Real Example: I once worked on a land clearing project where the crew was using dull chains. The saws were constantly bogging down, and the work was slow and exhausting. After sharpening the chains and teaching the crew proper sharpening techniques, the work became much easier and more efficient. The crew was able to clear the land in half the time, and they experienced significantly less fatigue.

5. Air Filter Maintenance: Breathing Easy

A clean air filter is essential for proper engine performance. A clogged air filter restricts airflow to the engine, which can lead to reduced power, increased fuel consumption, and overheating.
