Stihl MS 661 Problems and Solutions

The Stihl MS 661 is a powerful chainsaw that is known for its durability and performance. However, like any tool, it can experience problems from time to time. Here are some of the most common problems with the MS 661 and how to fix them:

Hard starting: This is one of the most common problems with the MS 661. There are a few things that can cause this, including a dirty air filter, a bad spark plug, or a flooded engine. To rule out the air filter, simply remove it and clean it with compressed air. If the problem persists, check the spark plug for damage and proper gap. If the spark plug is good, then the engine is probably flooded. To clear a flooded engine, hold the throttle trigger fully open and pull the starter rope several times. This will help to clear the fuel from the cylinder.
Rough idling: This can be caused by a number of things, including a dirty air filter, a bad spark plug, or a lean fuel mixture. To rule out the air filter, simply remove it and clean it with compressed air. If the problem persists, check the spark plug for damage and proper gap. If the spark plug is good, then the fuel mixture may be too lean. To adjust the fuel mixture, consult your Stihl chainsaw owner's manual.
Poor acceleration: This can be caused by a number of things, including a dirty air filter, a bad spark plug, or a clogged carburetor. To rule out the air filter, simply remove it and clean it with compressed air. If the problem persists, check the spark plug for damage and proper gap. If the spark plug is good, then the carburetor may be clogged. To clean the carburetor, consult your Stihl chainsaw owner's manual.

In addition to these common problems, the MS 661 can also experience other issues, such as chain derailment, overheating, and engine failure. If you experience any of these problems, it is important to take your chainsaw to a qualified Stihl dealer for repair.

Here are some additional tips for preventing problems with your Stihl MS 661:

Use the correct fuel mixture: Stihl chainsaws require a 50:1 fuel-to-oil mixture. Using the incorrect fuel mixture can damage the engine.
Change the spark plug regularly: The spark plug should be changed every 100 hours of use. A dirty or damaged spark plug can cause a number of problems, including hard starting, rough idling, and poor acceleration.
Clean the air filter regularly: The air filter should be cleaned every 25 hours of use. A dirty air filter can restrict airflow and cause the engine to overheat.
Store the chainsaw properly: When storing the chainsaw, make sure to drain the fuel tank and oil tank. This will help to prevent fuel and oil from evaporating and gum up the engine.

By following these tips, you can help to keep your Stihl MS 661 running smoothly and prevent problems.
