New wires, new plugs, looks great, timed at idle and purrs like a kitten. Problem is as soon as you give it some gas it back fires. Replaced vacuum advance hose still undrivable. I would have already put the old one back on but I had to remove the gear, which is rivoted on with some little shims, for the new distributor and didn't want to go thru that pain again. Any thaughts, experiences, advise would be appreciated.

Might check the mechanical advance to see if it's sticking. Would help to know where the back fire is coming from though.
