Chainsaw Won’t Start When Hot?

chainsaw won't start when hot

This could be due to a variety of reasons, such as fuel related problems, an issue in the ignition system or the engine becoming too hot. To diagnose the problem and determine the best course of action, contact your manufacturer for technical support or take it to a mechanic if necessary.

While this can seem like an exasperating issue, there are a few steps to take that may help get your chainsaw going again.

1. Restricted fuel supply

Check for a restricted fuel supply. This is the most common cause of a chainsaw that won’t start when hot. You might be able to see signs of this by checking the primer bulb, or if it’s not visibly obvious, then check with a mechanic or get in touch with your manufacturer for technical support.

Changing the air filter, cleaning the fuel lines and ensuring that the tank is completely full of clean fuel can help get a chainsaw moving after it has been heavily used.

2. Vapor lock

Another common issue that can cause a chainsaw to fail is vapor lock. This occurs when the fuel in the tank heats up and becomes a gas, preventing it from flowing through the carburetor into the engine. To diagnose this problem, try removing the spark plug first and then pulling on the starter rope. If you get a big puff of fuel, this is a common sign of vapor lock.

To solve it , try re-priming the engine and allowing it to sit for a few minutes before trying again.

3. Difficulty in the ignition system

The common problem that can occur is an issue with the ignition system. This could be a broken spark plug, a faulty ignition coil or even a loose connection somewhere in the wiring. To check for this, use a multimeter to test each of these elements and identify any faults.

4. Carburetor

There can also be a problem with the carburetor, usually caused by dirt or debris that has become lodged in it. Take a look at the carburetor and clean any of the ports or jets if necessary.

To clean the carburetor, use a carburetor cleaner and a can of compressed air to blow out any dirt or debris that may be causing an issue. Once the carburetor is clean, reattach it to the chainsaw and try starting it again.

5. Overheated engine

Finally, it’s possible that the engine has become too hot. To cool it down, switch off the chainsaw and let it sit for a few minutes before trying again.

Chainsaw Cooling Techniques

There are some cooling techniques you can use to avoid problems with your chainsaw becoming too hot.

  1. Make sure to take regular breaks to allow the engine and parts of the chainsaw to cool down.
  2. Keep your chainsaw well-maintained with periodic oil changes, air filter cleanings, spark plug checks and other services as recommended by the manufacturer.
  3. Avoid running your chainsaw for extended periods of time without taking a break.
  4. If you’re using the chainsaw in hot weather, try to work in the shade and take breaks often to help keep the engine cool.
  5. Inspect your chainsaw regularly for any signs of wear and tear, as this can cause it to overheat more quickly than normal.
  6. If your chainsaw does become too hot, switch it off and let it cool down before using it again.
