5 common Reasons Why Your Chainsaw Won’t Start

Here are top 5 most probable causes.
1.Defective spark plug
Due to carbon buildup and a weakened electrode, the spark plug will degrade over time which can prevent the chainsaw from starting. You should inspect the spark plug for damage or wear and you can also use an ignition tester to help determine if the spark plug is defective. Generally, we recommend replacing the spark plug once a year.
 
2.Restricted carburetor
The residue that results from old fuel being left in the tank can create a restriction in the carburetor. This is why you should always use fresh fuel when filling the tank and a fuel stabilizer to help maintain the quality of the fuel. For better stability, you can use a pre-mixed fuel and oil product that is ethanol free. You can try cleaning the carburetor with carburetor cleaner to eliminate the clog. If cleaning is not effective, you can often purchase a carburetor repair kit to replace some of the components or install a new carburetor altogether.
 
3.Clogged fuel filter
Old or bad fuel filter can also create a clog in the fuel filter which can prevent the chainsaw from starting. We recommend replacing the filter with a new one.
 
4.Broken recoil spring
If the starters recoil spring is broken, the rope won’t be able to recoil on to the pulley, resulting in the chainsaw not starting. Many recoil springs can be replaced individually but it may be easier to replace the whole recoil starter assembly.
 
5.Malfunctioning recoil starter
The recoil starter itself could be malfunctioning and unable to engage with the chainsaw engine crankshaft again. The starter assembly can be replaced to solve the problem.
