A Series of Unfortunate Events

Well, I believe all my problems have come to a pinnicle.

If you read my other threads, you'll see that I am having issues and can't seem to find the culprit.

1] Can't accelerate past 1/2 throttle.
2] Very rough engine at 1/2 throttle.
3] Sheared a mounting bolt.

And now this, I sheared another (the other rear) mounting bolt!!! OMG! I want to scream! :-||

Well, luckily when I bought a replacement for the first, I bought 3 extras as well. So in the process of replacing this one, I noticed my rear freewheel hud was off the axel. The nut that keeps it in place had come loose. It looked as if I had also lost some bearing in the rear axel area. So after I tapped and removed the sheared mounting bolt, I took the whole rear wheel assembly to my local bicycle shop. Surely, they would be able to properly reassemble the rear hub. I took it in and the guy said that I had completely shattered my rear freewheel assembly. I figured as much.:( I told him to replace the freewheel hub and overhaul the bearing/axel.

Now, I wonder. If my rear axel/hub was so bad, could this have caused the mounting bolts to shear? And if the motor is properly mounted/stabilized, could the excess vibration cause the motor to have a low RPM limit?
 
That's weird.....your freewheel has zilch to do with the bolt on sprocket engine drive.
 
some of these engines have bolted on flywheel weights and some have let go making for a very rough and shaking engine at least I've heard that. I think they might be the so called 80cc engine from kings but not sure.
 
if my rear axel was all messed up, wouldn't bad angles and such from the chain to the motor be a possible cause for shearing off two mounting bolts?
 
Your axle breaking might cause an issue, but you aren't going far in that condition and it certainly wouldn't make your engine rough with the clutch in. It could indeed be your flywheel counterweights.....wow. Bummer, dude.
