Most Common Reasons Of Chainsaw Throttle Not Working

The throttle cable is a vital part of a chainsaw, and if it becomes dirty, it can cause the throttle to stop working. To clean the throttle cable, you will need to remove it from the chainsaw. Once the cable is removed, you can use a brush or a rag to clean the dirt and debris from the cable. Be sure to lubricate the cable before reinstalling it.

Throttle Cable Stretched

Over time, the throttle cable can stretch, which can cause it to become loose and not work properly. To check if the throttle cable is stretched, you can try to pull the throttle trigger and see if it is difficult to move. If the trigger is difficult to move, you may need to replace the throttle cable.

Throttle Cable Binding

The throttle cable can bind if it becomes kinked or twisted. This can prevent the throttle from working properly. To check if the throttle cable is binding, you can try to move the throttle trigger back and forth. If the trigger is difficult to move, you may need to lubricate the cable or replace it.

Throttle Housing Damaged

The throttle housing can become damaged if it is dropped or hit. If the throttle housing is damaged, it can prevent the throttle from working properly. To check if the throttle housing is damaged, you can look for cracks or other damage. If the throttle housing is damaged, you may need to replace it.

Throttle Linkage Damaged

The throttle linkage is a series of parts that connect the throttle trigger to the carburetor. If the throttle linkage is damaged, it can prevent the throttle from working properly. To check if the throttle linkage is damaged, you can look for loose or broken parts. If the throttle linkage is damaged, you may need to replace it.
