I have a used zoom cycle 80 (66cc) motor and I installed it on a different frame. Turns out that the seat tube was thicker than a stock set up,So I filed the seat tube mount wider so it would fit. Later it brakes and shortly afterwords one of my 6-mm engine studs brake.
I grab a hold of the other one with a vice-grip to unscrew it and it brakes of just about flush with the motor. Then I try an easy out on it and it brakes off before it moves at all.
So now I dremel the block flat and move down about five millimeters and drill a new set of holes and tap them so I can put some new 6-mm threaded rod in the new holes. I then built a new clamp out of square steel tubing with a notch cut out of it so it fits the wider seat tube I also reinforced the holes with some steel spacers made out of 6-mm tubing.
The engine seems to turn freely when I turn it over with a socket on the drive sprocket and I think I still have compression.
Is there any hope that this will last longer than the part that failed or am I just wasting my time? Any clues ?
