check to see if the pin sheared in the distributor

Yes, you possibly have a blown power valve (at least) in the carb. Anytime the motor backfires like that, your going to cause damage to the power valve if there is no blowout protection kit in the baseplate of the carb. You'll also find that if there is a brass float in the carb, it may be crushed or dented badly now, causing you to have a much higher than normal float level, which will also contribute to your overly rich condition.
At the very least, I'd recommend pulling the carb apart and going thru it.

Let us know what you find.

Hope that helps,

Check you distributor pick-up coil ,mine was bad right out of the box and it was the last thing we checked cause it was new but it was the problem.

Timing chain?
Fuel pressure?
Valve Train?

wheels, it does sound like it could be a ground problem. be sure that you have a ground strap from the engine to the frame, even if you have solid mounts.

This is what we found last night------we put a volt meter on msd box.....when we try to fire it we have a sudden rise in volts then goes to 0. It trys to fire once then nothing. Wheels "volunteered" to hold a screwdriver in coil wire and press against distributer. We get a quick light spark, then nothing. I checked all the grounds and cleaned ends, still nothing. I talked to my engine builder, he says it almost has to be ignition, not internal engine problems. I had a spare distributer that I know works and put it in with no change. Only thing left is msd, coil, and battery.........changing everyone tomorrow night!!!!!!

This sounds like somthing that has happend to me and a buddy of mine. Do you have a blaster 2 coil? I have had one go out on me and so did a buddy. It started acting up first getting a poping like misfire...then ran a bit more then just went dead. The one was only 5 races old and the other about a season old.....since then i have only run blaster 3 coils and had no problems at all. People allways say a coil works or it doesnt well we both had them act up on us befor they went bad alltogether i changed the msd befor going to the coil that was only 5 races old wich cost us a main event. Hope you get it all fixed.......

I see you got her fixed .I wanted to add something for future reference.I have seen others have problems with ignition switch loose connections or corroded causing missing and popping on the track.

Thanks dirtracer7--we may just have to replace that switch also just to make sure we have all the culprits that saddened us 2 weeks ago-- (got rained out this weekend)

thanks Wheels
