what should the off idle vacum be with the car in drive? sorry forgot to put that on the last post :shock  

have not checked the off idle vacum, but i will. how would i check for leaky throttle shaft or bad throttle shaft bushings?  running points , maybe i should go get a new set.

i went out today to work on that carb, i bent the pump rod so that it would squirt as soon as i hit the throtle, same result? checked the vacum on my gauge, at idle it is pulling 21 in. hg. took the carb off took it apart to check the pump circuit took out all the springs, check balls, etc. cleaned everything and checked all the passages and cleaned with carb cleaner and compressed air, put it back together hokked it back up to the car, same result? :?  this thing is driving me crazy because i cant figure it out. i appreciate all the help you guys have given! but i am learning more about how carbs work and im getting alot faster at taking that carb on and off

been working on my 55 olds(324 ci) had a problem with an off idle stumble with the rochester 4gc carb. so i rebuilt it took it all apart cleand everything and replaced springs , check balls etc. also cleaned my gas tank, ran new fuel line, and replaced the fuel pump and filter. i reinstalled the carb today, stated fine i shifted into drive and and barely touched the gas and the car stalled. what would cause such a thing. any help is appreciated

im building a 1955 olds super 88 4 door. just trying to get the motor back together trying to be ready for the spring but have alot of long nights ahead of me.

just another new guy in search of good info from hot rodders from all over. and maybe help a few along the .im from greenville sc. glad to be aboard.
