Hi, calling on the gods of all things gas-powered, here. My ten year old Echo blower runs great but, eventually, dwindles down to a sure death. I changed out the carb and it then ran a few extra minutes but still died. I hypothesize that the piston ring is worn down, after ten years, and when the motor heats up compression is no longer possible because the ring is no longer snug in its heat-expanded cylinder. Am I correct, or is there another possibility?
