Could be the trigger points. There's no good way to test them, though. I was having a similar problem, and my heat exchangers were loose. Torqued them all to 16ft/lbs and it fixed it right up. Have you checked the plugs? It could be running lean or rich. I can never remember which one it is that makes it backfire.

Good luck,
