hi guys i have installed a dual fenton intake from speedway on a stock splitted exhaust manifold and i bought new weber carbs from langdons.1954 235 engine..

engine idles fine but is bearly driveable
it hesitates and stumbles bad and will bearly pull the truck forward.. i had some issues with dirt in fuel line so on initial fire up on carb was clogged up.
i have taken the carbs apart and cleaned them out (god enough i think) jets look fine..
