Old thread, and sorry to revive it.. I have a question for those that have run it though.. I had a problem with mine wearing the brass bushing on the conecting rod, crankshaft side.. Also when I tore it down I measured the crank pin, it had .0055" roundness, and .011" taper from rear shoulder to edge of pin.

OS wouldn't give me any info weather it was okay or not.. I know it is bad. But curious if anyone else has run into this problem, and what all has been done, if anything, to fix it..
