I would say you must have the distributor in correctly (not 180 degrees off) if it starts and idles. From there I would try advancing it a little at a time. I do not know how much you know about this so I will explain as if you know almost nothing! To advance it you rotate the distributor counter clockwise (as viewed from the top). If it seems to idle better each time you advance it, keep trying to see if the backfire is still there. When it idles, is it smooth? If not, have you double checked that you have all the plug wires on in correct order on the cap?

I don't think you need to find TDC because I think you have it in right, just need to adjust it for the right advance. Making sense?

That sounds like the correct way to put wire ends on. Strip the insulation, fold it back, install the terminal and crimp.

Ok, if the vacuum advance is hitting then you need to take it out and reinstall it farther back so you can adjust it more. I do it the weird way (so they tell me!) Hope I can explain it right...

1) Remove distributor

2) Take a long flat screwdriver and put it down the distributor hole, turn the oil pump shaft about 1/8th of a turn clockwise.

3) Drop the distributor back in remembering that it will now be moved back about one complete cylinder ( for example, if the rotor was at terminal #1 on the cap before, it will now be at #8 on the cap)

4) Most likely now you will have to pull it back a bit towards #1 (or wherever you were at) to get it right but at least you will have more adjustment for advance.

Clear as mud?

Hey, wait a sec. The pump shaft needs to be turned clockwise!!! I said that wrong and corrected my post!

if the oil pump shaft is causing concern, you could just lift the distributor enough so it disengages from the camshaft, turn it one tooth clockwise and reinstall. The distributor may not go down all the way because of the oil pump shaft, but turn the engine over a bit by hand (1/4 turn should do it) and the distributor will drop down to mate with the oil pump shaft.

That's the same way I do it... it's nice to have someone hold the distributor down gently when you bump it over so it doesn't jump up (which you might be able to do by yourself by using the hold down and a longer bolt -hope that makes sense).

Do you have a timing light? Would be good to check the timing if you have it running...
