Car stalls when I give it gas, ideas?

[rIbBaD]

Well, 3 weeks ago I started driving my 86 Cutlass as a Daily, and I've had nothing but problems with it since I started driving it, I've almosted been tempted to just sell it for the 2 grand I was offered. But I love the car to much to sell it so I've gotta stick it out and just keep fixing the problems that surface..

Anyway, heres my problem. When I give my car gas it stalls, however if I stop at a red light/stop sign/whatever, and pump the gas a bit it doesn't stall, but then I have literally zero acceloration, I've got 80 year olds flying past me when I'm trying to get going, but once I hit about 50 KM/H my car accelorates fine, its just when I stop and then start again that my car stalls, once I hit about 40/50KM/H it seems to run better.

Any ideas what my problem could be? If you need more info I'll be checking this thread often in an attempt to find out what is wrong and can provide you with more info.

Thanks,
Riley.

Edit: My car also runs extremely rich, not sure if they're related. After doing some research I believe it may be my timing, what do you guys think?

What kind of carb you have in it? I would start there, it could be the accelerator pump.

I have a factory 4 barrel carb, I got it proffesionally rebuilt about a year and a half ago, however after I got it rebuilt it sat for a year and a half until I started driving it again 3 weeks ago.

The first thing that i would try is spraying the whole carb inside and out with carb cleaner spray it into the throat of the carb while it's running and give it some throttle at the same time because it will want to stall on you. Just spray it real good inside then outside then take it for a ride and open it up on the highway to clean out anything that might be clogging it. I've found that todays gas with ethanol really does a number on a carb as far as gunking it up.

Thanks for the advice just picked up a can of carb cleaner going to try that after work I'll let you know how that goes.

Sounds to me like it is flooding out. I would bet that the carburetor is gum'd up quite a bit from sitting around so long with gasoline sitting in it :idea: You will probably have to dissassemble the carburetor and clean it thoroughly. Checking the timing is not a bad idea either

 

[rIbBaD]

If I disassemble the carb do I need to replace the gaskets even though the car has only been driven once since they were last replaced (which was a year and a half ago)?

Also what should I use to clean it when/if I disassemble it?

 

[RITTER]

If you are very careful, during the dissassembly, you should be able to save the gaskets. Just use a standard, off the shelf, carburetor cleaner (from NAPA of course )

Well I used about half a can of carb cleaner and took it on the highway and still nothing. Hopefully I'm going to borrow a friend of mines timing gun tonight and check that, also another thing I noticed is it seems to run pretty hot. Not to mention it burns oil. I'm in the process of rebuilding a 350 for it but I'd still like to figure out these problems for future reference. Any other ideas?

How does it Idle? It sounds like it could be a vacuum leak , as long as your getting a timing light check it and while your under there check all the hoses and ports on carb.
