Thermo Quad Help!

I ment to say that I can rev it up and hold it at a high Rpm, then for no reason she'll die. lack of fuel makes sense, but it has fuel when I look in the carb, but it also backfires a little. I've adjusted the distributer till it seems perfect. lol when I adjust the carb it either gets too much, or too little. strange, but I'll try it some more. lol gotta love your mopar!
