Hello, I have a 350 chevy engine with a fairly standard carter AFB carb. I have been having trouble for some time figuring out why one side of the carb will not provide enough fuel at idle. If I squirt fuel into the left side of the carb the engine idles normally, when I stop it starves the 4 cylinders fed by this side of the carb. The engine has an intake that separates the plenum under the carb so each side of the carb supplies only 4 cylinders. When no fuel is added to the left side the cylinders fed by it do not fire which I checked by pulling wires to those cylinders and there is no change in engine rpm but there is very noticeably with the right side. I have dismantled, cleaned and rebuilt the carb and nothing seemed to change. Any help will be very much appreciated. Thank you!
