sounds like your close,stop have a beer that your neihbor bought.recheck every thing. these old beasts can run with two plugs cross wired.if your timeing gear was bad you would of heard a lot of racket coming from the front of your motor like the a way bad water pump or alt. breanings sounds just before they fail.sounds like your one tooth off on your dist or 180 out.like wrechbender said mark your timing ball so it is easy to see. reset dist. check fireing order. I've been down this road my self.I've never be so sure about being right,except when I was 100% wrong.rechecking can be humiliating. humbly Floyd
