I have a Craftsman 25cc leaf blower that I have been struggling with. I have taken a lot of advice here but still can not get it to start. It has spark, the carb 'looks' clean (no gunk), I can see gas pass through the tubes from the tank to the engine, and the oil/gas mixture is correct. The only thing I don't know is the compression nor do I know how to check that.
Any suggestions for these symptoms? Thanks!
