It has a stock mechanical fuel pump on the block, we have not yet fired it because we tore the carb apart to check for bad needles or seats or anything that doesn't look right, one of the floats was way out of adjustment but that was about it, now we are going to rebuild it today with a full rebuild kit, we are also going to change the oil incase any of the fuel managed to seap passed the rings, we also need new plugs as we had to break two of them off because of shitty header manufactures that don't bend them right to get half the plugs out unless you have a thousand and one differant wrenches or something.
Would a stuck needle or seat cause the gas to drain into the cylinders?
