.......Based on what you have said...(runs fine at under 4000 rpm)...and your previous under hood excursions,,,,I think that your troubles are all in the distributor....it,s intermitently grounding out, or the advance mechanism is sticking and not advancing.....or.....sticking in the advanced position....It may be time for a new distributor....They do wear out.

No...runs fine at all parts of the curve until it starts doing its funny business. THEN, if I let it go back to idle or keep it at 4,000 and above she will recover.

ROB WAS RIGHT. I went through everything on or near the dizzy, and noticed the condenser was touching the support for the accelerator cable. I moved it away. Also made sure all of the wires to the coil were tight. Then I ran her in the garage. 5 minutes at idle, 5 at 2,000, 5 at 2,500, 5 at 3,000 and 5 at 4,000. Twenty five minutes without even a hiccup or burp. So, I hit the open road for some "real life" situations, trying to see if bouncing around and putting a load on the car (hills and turns) effected her. Well, she did make her occasional small backfire once in a while, but she seems to be back to normal. Drove her another half hour. Couldn't have done that yesterday without crapping out 2-3 times after violent (and I do mean violent ) bucking and explosive backfiring.

Even thought the insanity has been cured, she still does backfire once in awhile, and I've isolated the circumstance. Maybe some Carb guru can enlighten me as to what might be the problem:
I'm doing about 2,800-3,500 RPM and slightly let off the gas...maybe to cruise down a hill or just coast along. If I then give it slight throttle, it'll most likely backfire. If I give it more than slight throttle, it does not. Any clues there? |

Really? I thought exhaust leaks showed up on decel not on accel? Am I wrong about that (like many things automotive)?

I can see where you got that but I specifically said, "If I then give it slight throttle, it'll most likely backfire", which makes me think it's not exhaust leak since it is doing the backfire upon application of throttle...mild acceleration. Does not do it on decel or heavy acceleration.

A small fart or two on slight acceleration only after she's been riding along at steady throttle. Never under heavy acceleration and not under deceleration.
