i dont know if you remember my last post, but i was looking at buying a car, well i did. the idle was way off before. it wouldnt idle below 3000. i found a vaccum leak at the intakle manifold. i had to make gaskets for both sides of the plastic spacer/heat shield between the carb and mani.

the car will idle at about 3000 when choked, but once it warms up, it wont idle. when i start it, it goes to about 1500 then wnats to die, i have to throttle it to keep her alive. i adjusted the idle the best i coudl with the speed/mixture screws. but i still cant get it to idle. i got it to lower when i start it, as low as i can, but it wont idle. when i get home im gonna checl the linkage. what do you think it could be.

i thought maybe driving it would help, it didnt. when im hardly pressing the accelerator, the car goes slow and bogs, then i have to press the gas harder, and it like frees up then the car goes.

any ideas?

It could be a couple of things but check for vaccum leaks around the carb,or caps missing on the carb.

Yeah, vacuum leak.

i brought it down, but it wouldnt idle. you think thats a vacuum leak? i figured it was something in the carb, so im putting my old carb on there.

update. has to be a vacuum, i put the old carb on, and its doing the same thing. so tommorrow i get to find that.

Spray carb cleaner around and it should change the engines speed when it hits the vacuum leak. It could also be the intake. I had a car with a loose intake once. It had a little pool of antifreeze where the intake and engine meet.
