You may just have a heavy or sticking float, or debris under the needle valve.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Could very well be, but I replaced needle and seat and was very careful to keep it clean. I'll check it and float. Thanks

If it is, would that cause it to stumble and want to die when I press the gas though? I can't even get it to 1/4 throttle and had to pull out in LOW

The way you described it the carb is flooding.  Did you overhaul it?  How was it running before?

Yes I rebuilt it. It ran like crap before....spitting and sputtering. Backfiring at times. My dad said it never ran right since my papaw bought it new. Part of the problem is that it rarely went over 30mph and was always on dirt roads. And the smog pump was burnt up too. I've don't several carbs in my day, fixed one other monojet besides this one but never rebuilt a monojet, mainly holley's, Edelbrocks and rochester 2Gs along with farm equip carbs
