Hey all. I'm a tech that runs a mobile service but i never have dealt with the "4 stroke type" two strokes. I have an EB8510 that had so much carbon buildup it was hanging up the exhaust valve. I removed the head and did a valve job. I'm back to the point of reinstalling the belt and it occured to me it would have to be timed correctly. I didnt see any hash marks like on a camshaft, and i dont know any local shin techs to ask locally. Anyone?
