first off hello to all i am glad i finally found a good forum for these vehicles. i am currently looking at buying a 1963 f100 that has a 59 bed on it. lowered, painted white with red scallops, steel wheels, sombrerro hubcaps, and white walls. anyways the owner drove it all over last year to shows then all of a sudden the fuel pump went out. thinking it was the carb he got a rebuilt and stuck it on. no good so he swaped to a holley blue elec pump with regulator. since then it will start but not idle at all. i e-mailed him this mornning to try and find out exactly what carb it is and go from there. he said currently he was trying 3 lbs but it still floods. now i noticed looking at the carb from straight on there is a large brass tube comming out the right side near the top of the carb (this is if you were facing the engine from the front) that is wide open. i am asumming this is a vac line for something and i would asume that it would mess with the way it runs. any ideas? oh it is a otherwise stock 223 that he said ran great before having fuel issues.
