ROCHESTER Quadrajet 4mv (7045583)
I think the Chevy (carburetor) is getting too little fuel when accelerating.
New acceleration pump seal installed.
Cleaned the carb, ultrasonically cleaned.
As the RPM increases, there is enough fuel.
what could it be?
Power piston,
Is the power piston supposed to be like this poicture, or is it damaged?
