I was bucking up some logs this afternoon after putting in a new primer bulb, and the Earthquake just stopped running - no noise, no flying parts. I pulled on the cord once, and it turned over, then froze. The autopsy revealed that the wrist pin retainer clip came off and became incompatible with the moving parts - namely the piston. The jug is scored and punched too. I'm feeling sad, as it had been my first stab at porting and squishing and was running a 16" bar like a little beastie. It gave me 20 cords of firewood and some fun tinkering for $36. I'm going to miss it. Anyone need some parts?
