hey, i have a '62 falcon 144, w/ the same problem, i just had it rebuilt last year, and it hesitates and wants to/ will stall if u give it decent throttle, i have a good mechanic, and we have gone all through everything, and the only thing we can come up w/, is that the accelerator pump is too small, causing it to quit, were currently making an adaptor and adding a weber 2 barrel, which should hopefully solve the problem, but another problem is todays gas, and the octane being so much lower than when our cars were made, and especially with the small sixes, you notice it a lot more than w/ a V8, all i run is premium, and if i had the money, id run a load of race gas (105 octane) in it, which would make it run like a top, but i dont have the $5.50 a gallon to buy it, and thoes octane boosters are junk and a waste of time. when i get the 2 barrel on, ill post a reply with wether it worked or not, and if u have any ideas or new info, please share!
