If your chainsaw is not starting when you pull the starter rope, and you've checked the above, there may be a problem with the compression. A petrol powered chainsaw has several moving parts. To keep these parts moving, a certain amount of compression is needed.
Compression is generated by the engine via the crankcase and the combustion chamber. When compression is too low, you may experience decreased power or complete shutdown because the engine isn't able to hold enough pressure in the cylinder to run efficiently. A simple way to check for low compression is to place the chainsaw on the ground and use the starter rope to lift it.
Good compression will prevent the rope from pulling out. You should be able to carefully lift the weight of the chainsaw by the starting cord. If you do notice the rope slowly extending, then the chainsaw compression is most likely low and needs checking more precisely.
