While crusing around last night, I nailed it really hard in second gear. As soon as I let off, it backfires out of both pipes and died. I thought it would have something to with the dist., so after I pulled it it was obvious the rollpin had sheared through the gear. My question is; I have two pins, a
zinc coated silver one and a black one. I believe the black one is hardened and is the one I want but I want to be sure. So which one do I use?
Thanks,
Tim
