CARB talk!

now tell me whats up with the 650 Carter i hav on it now,the car fired on the first crank no probs. but 15-20 sec later,she started to surge,an jump from what i though was around 900-1200 rpms at idle we all had no clue what was going on an we had two full auto freaks with the start up,an no one had any idea what was going on :scratch: but if we blip the gas she was crisp an right on tap like a healty motor,but come back down to idle an she started to surge agian,we shut her down for the night,then today i was thinking that we had the Fuel Reg. set up diff since the last run the motor had so we ran it an ajusted that an she held a strong idle at around 800-900(no tach)ran it for about 10 min.shut it down,got all happy that we fixxed it then my mom came home an she wanted to hear it so fire it back up an it starts to surge agian :scratch: so we gave up on it for today till tuesday when i hav time to put the new carbs on.So what do u guys think was going on with it?
