I’ll explain what the primer bulb does, how to identify a faulty primer bulb, and how to fix the problem.

Why Chainsaw Primer Not Working

Reasons why chainsaw primer not working

Clogged primer bulb. The primer bulb is a small rubber bulb that is used to pressurize the fuel system. If the bulb is clogged, it will not be able to pressurize the fuel system and the chainsaw will not start.
Low fuel level. If the fuel level is too low, the chainsaw will not be able to start. Make sure that the fuel tank is filled to the proper level.
Stale fuel. Old or stale fuel can cause problems with starting a chainsaw. If you have not used your chainsaw in a while, it is a good idea to drain the old fuel and replace it with fresh fuel.
Dirty carburetor. A dirty carburetor can also cause problems with starting a chainsaw. If the carburetor is dirty, it will not be able to properly mix the fuel and air, which will make it difficult to start the chainsaw.
Bad spark plug. A bad spark plug can also prevent a chainsaw from starting. If the spark plug is not firing, the chainsaw will not be able to ignite the fuel and it will not start.
Corroded spark plug wires. The spark plug wires can also corrode over time, which can prevent the spark plug from firing. If the spark plug wires are corroded, they will need to be replaced.
Improper carburetor adjustment. The carburetor may need to be adjusted if the chainsaw is not starting properly. The carburetor controls the amount of fuel and air that is mixed together, and if it is not adjusted properly, the chainsaw will not start.
