I thank you for the info, yes you are right (at my age I'm still learning.) I only had this
80 cc for a short time , on the second run with in 5 miles or less there was some major crunchis happened from the engine, when I got it home I remooved the clutch housing cover there were 2-3 dozen tiny ballbearings , the clutch gear and the smaller gear was badly damaged. After strugeling to remoove both gears I thought since turning those shafts I possibly got things out of time. How ever the engine at this time is runable how ever it kicks back on the first turn or so , and it seems it will not reach top RPM
I thank you verymuch for your info again your explonation has being the most clear and simple, and correct.You have no Ideal what different opinions and recomendations I received.
