I was on my way to work on my motorized bicycle and the engine just died out of nowhere. I changed the spark plug and put a brand new cdi on and still won't start. Took head off and yeah there's a little carbon buildup but no scoring. Cleaned air filter and checked to make sure there was fuel and there was. It definitely has compression because it is very difficult to pedal and i can hear it. I am not understanding what is going on. I do notice there's a metal thunk when im riding it while the clutch is both engaged and disengaged. But other than that I don't see a reason for it not to start back up. The sound seems like it's coming from the crankcase so I will try to take the motor completely apart tomorrow and the magneto and wires look good as well so I don't believe it's that but I would really appreciate some feedback as to what could be wrong. I haved looked all over forums for about 3 hours now and it seems like I can't find any answers so please help me out. This is my only way to get to work
