1970 Super 150, the engine was rebuild by Hotrod Al, 20/20 carb, sip exhaust, vape ignition and 177 cylinder kit.

It is running rich and stumbling with throttle.

Carb is a 20/20 with
idle jet 40/130
Air corrector 140
Atomizer E3
And jet is 120

Thinking of getting a richer idle jet and a bigger air corrector like a 160 and stepping the main to 113 or 112.

Unless others have suggestions. Thanks.

I'd start by sorting the main first. Drop it until it's not boggy. Then adjust AC, etc as needed. YMMV
