FZ340D motor Rebuild or Replace
 

I have a late 80's or early 90's club car. I believe the cam or something may have broke in the lower end. The crank probably will need turned or replaced along with a new cam. I haven't had any luck trying to find a replacement motor and it sounds like converting to a newer motor can be tricky. Looking for suggestions. Where can I find a rebuilt or used motor? Is it worth rebuilding?
