My chainsaw starts up, the chain rotates, then the motor immediately dies. This began after using the saw for a good hour. So, im guessing the carb might be clogged. I sprayed brake cleaner in the carb and cleaned the entire saw thoroughly. Now the motor doesnt even turn over. Even with the choke on it feels as if its not. I checked linkage and thats all good. can you help? Where can i find more info on cleaning out the carb.?
