What cause this. I am kinda learning on a trial and error basis here. I just rebuilt my carb and got it running halfway decent again. This car does not deserve to run decent. It should run like a bat out of hell! What causes this? Lean? Rich? I dont know.

It is a 750 dp mech secondary with a proform main body and quik fuel throttle plate
