The chainsaw must be using the correct fuel mixture of gasoline and oil. If the mixture is too rich or too lean, it can cause the primer bulb to not work properly.
Clogged Fuel Filter
The fuel filter can become clogged with dirt, dust, or other debris. This can prevent the fuel from flowing properly to the carburetor and the chainsaw will not start.

If the spark plug is bad, it will not be able to produce a spark and the chainsaw will not start.
