The main pulley on my TBI 305 seems to wobble. I also hear a bearing going bad. I havnt used a listening device to pin point the bad bearing but its close to the main pulley. Is this just a matter of replacing the pulley or is it more serious? Could somthing be wrong with the crank. /forums/images/graemlins/frown.gif Im not familiar with bottom ends. *yet* Has anyone had to fix this before?
