Every chainsaw relies on a spark plug to ignite the air-fuel mixture for proper combustion. Over time the electrode on the spark plug will burn away and the engine does not start. If the engine does not start, remove and inspect the spark plug. If there is any doubt that the plug is working properly replace it.

If the chainsaw won't start, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the chainsaw for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor and it can be difficult to burn making it hard to start the engine. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor with carburetor cleaner. If that isn't effective, replace the entire carburetor.
