2100 carb conversion issue

[Dan77CJ7]

Thanks guys. I will try having capping all the ports tomorrow, and see what I get. Just for clarification can I cap the PCV for this test, not sure if that will cause other issues or not.

I do have the return spring on, maybe it is not tight enough. I will play around with that tomorrow too. When you put the return spring on did it immediately fix your problem? That gives me some hope that there is something small that I can correct, and be back running.

You'll need a good return spring, i made a bracket so i could get a good strong return,(i like a stiff pedal), when you hit the throttle by hand it should SNAP back. all the way back, IMO if your using the stock throttle cable chances are you need a stiff spring. on mine the pcv runs to the back of the carb? my old weber ran the the spacer plates they leaked really bad. heres some pics that might be helpful,
