I have not even a year old Craftsman chain saw, 2cycle 42cc motor, 18" bar. It worked OK until now. Since day one, after it got hot from few hours of use it wouldn't start. It would always start the next day though. I used it a LOT last night for about three hours. It died yesterday and wouldn't start. I couldn't finish the job !
This morning I go finish the job and it won't fire! I spent an HOUR trying to get it to run. I checked the air filter, which is clean, checked the carb which is clean and getting fuel. Checked the spark plug which sparks. It has brand new gas with 40:1 mix.
The only thing I can think of is that it doesn't have enough compression to start.
