ok, i know just about nothing about carbs... and my car is now idling at about 500rpm... i dont know what i did to cause it (as i said i know nothing about carbs) and i was wondering how to get the idle rpm up

Hey..Find the intro section before asking for help! lol jk :thumbs: I'm not too sure of the setup on that model but on the carb (under the air filter box) there should be an emisions screw which controls the emissions and in tern the idle of the car, bear in mind that the idle only needs to rise a little bit (to around 850 rpm, or maybe a little less even)

k, should i tighten it or losen it?

Before you turn anything you need to determine what the problem is. The way I interpret your first post is the idle speed has gone down. Is that correct. If so find out why BEFORE adjusting the idle speed.

well, i got it fixed... it actually had nothing to do with the idle... it was the carb... it was extremely dirty and it was just messing it up (i had my neighbor help when he got home) i guess i need some new silicon hoses as well, he says there is a bunch of leaks. so, id just thought id fill you in with the info.

Glad you found the problem - vacume leaks are one of the most common causes of idle problems

That's familiar to me :rolleyes:
It happened to me some years ago with another car. The idle problems disappeared when I decided to repair the carburettor. Once, at an altitude of 2000 meters (about 6000 ft) I got 400 rpm :eek: Definitely, it needed to be repaired.

Cant u interpret other peoples questions too? Instead of demanding for more info/facts????

Sometimes facts are important to make sure a question is understood, a problem is well defined, to know what kind of car one is dealing with, or to know if the modifications someone is asking about are legal or will get one fined for removing emmissions equipment

Some facts are important any time one posts a question about a specific problem such as make, model year, build date (sometimes very important), engine, tranny, special packages,etc.. For example if someone were wanting to discuss Ford Crown Victorias, I would want to know information such as this is a 1992 Ford Crown Vic LX (P74) 4.6L V8 built after February 1992 or this is a 1998 Ford Crown Vic (P71) Police Interceptor 4.6L V8 since this info tells me something about the car and gives me a good idea of how the car is equipped and also gives me a good idea of how to suggest a person begin troubleshooting the car.

If someone were wanting to discuss carburators, I would want to know if somethings such as this is a 1978 AMC Concorde with a 258 CID L6. Knowing this type of car, I would probably ask an open ended question to verify we are dealing with a Carter 2bbl BBD series carb or if the car has had an aftermarket carb installed and other info before telling the person how to set the curb idle and high idle speed and coordinate this with the base ignition timing or where to look for common vacume leak spots.
