there all the same link

and i bought the Engine

Small end of the rod looks like its smoked...

that's what i thought its alot of black crap like carbon it comes off easily and the pin surface is still smooth

Think its residue from when it holed a piston?

I would flush out the bottom end good

its getting flushed out good

rebuild then sell as i got to many pistons and parts lying around doing nothing

what was the clearence for the weisco piston on a air cooled Engine?

.005 ?
