You do not need a new carb and you cannot buy a magic carb that will run perfect out of the box.
You need to dial in the one you got ..The problem is more if a ignition set up problem than the
Timing curve, base timing at idle??
what carb model number pri jets sec jets,,, power valve.
What intake manifold? Auto trans? Converter stall speed? manual transmsision?
Fill in the blanks.
Can show you how to set it all up to run clean, not load up and not foul plugs.
Its a matter of set up details not a i need a new carb problem.
The carb is not too big.
