I am the original owner of this saw and up to now have been more than satisfied with the performance. Never had a breakdown. Never had startup issues. I always kept it clean and made sure I used the proper gas to oil mix. I would even run the saw till empty before long periods of no use. Today is a different story. I cannot get it started. Tried a new plug, fresh gas, clean air filter. I have not touched and carb settings or tested any internal parts. Before I go back to the dealer, are there things that I can check myself? Just trying to save a few bucks without screwing it up.
Check for spark first thing. Once you know there is spark, remove the spark plug and make sure the plug and cylinder are dry (pull saw over several times and even use compressed air to dry out the cylinder). Put plug back in and drizzle a teaspoon or so of mix right in the air inlet of the carb, then pull over to start. It should fire on that mix that you dumped in and that will give you good impulse to the carburetor and will likely stay running. If it fires and runs a couple seconds, try that again. If all you get are a couple seconds of run time with the teaspoon of mix, it is likely a fuel delivery issue.
