My 1971 Olds has recently been hesitating when the gas is pressed, and keeps cutting out. this would not be a problem except that it is dangerous and otherwise annoying. if you know why it would do this, please let me know, would rather fix it myself than have a mechanic do it. *** have replaced fuel filter, pump.

 

What kind of carb are you runningand what kind of manifold?

 

im running a Rochester 2 jet and im not sure about the manifold

 

it sounds like a carburation issue to me, but i unfortunately am not familiar with that carb setup/brand...

 

is the carb and manifold stock?. You should be able to tell after market from stock.

 

the rochester is probaly the stock 2 barrel carb do you smell gas when the car dies ?

 

are you thinking that it is very over rich kwik? if it was very rich, it would carbon up and soot out the exhaust pipe like a diesel...

 

No Iwas thinking internal leak maybe accel pump ,power valve or maybe vacuum leak all can cause this problem but so can spent spark plugs or weak coil does your car have HEI with out the car being here in front of me its hard to tell.hope you find out what it is I just took a break from working on mine its a 79 H/O it needs everything but it will be nice when its done Good Luck my friend I've gotta get back to degreasing a 350 -Jim

 

sound like a accel pump to me. my ranger did it to. worked for me .but it's a 85 model.hope this helps. later

 

I now a little bit so first you should check all vacum line for leakes first idel the car and spray carb cleaner around all vac line start there
