i checked that out. Its the copper thing - OR its the thickness of the crank under copper thing
im gonna go scrounge one off another crank if i can find one.
Come to think of it the crank doesnt look like anything ive ever seen, there is a possiblity its different.
if it IS different, its going back in the magnum x kick motor and im putting the roller bearing crank in this motor. I really dont wanna have to pull the thing apart tho..
