When ever i start the car after a while like overnight or after work, my car doesnt turn over when i just turn the key. i HAVE to turn the key while pumping gas in, AND i cant just have it idle once on, i HAVE to rev it to 2500 rpm and warm it up, anything below 2000 rpm at start will stall the car. i HAVE to let it down easy until idle at 250 rpm then its totaly fine. total time bout 5 min, not bad but rather not have to.

whats wrong?

when i got the car i didnt have to do this, it just kinda started doing this 2 weeks ago.

everything is stock besides the new oil (gastrol 20w-50), all basic filters, and spark plugs i just put in.

are you using the choke? ...250 rpm sounds pretty low for an idle... try bringing it up to around 700ish rpms and see how it responds on cold start

250 is way too low. Adjust and let us know how it goes.

welcome to the world of owning a car with a carburetor.... its rare that i can get in a 7 and crank the engine and the car will start and idle rock solid at 750rpm and not have to pump the gas to get the engine started or have to hold the engine at 1500 or 2000rpm for a few seconds before it will idle.

Yea its the nature of the beast, use the carb, let it "idle" at 2000 rpm for a few mins to warm it up and off you go...

250 is cranking RPM. Something ain't quite right. Try adjusting the throttle stop up to at least 700. You might try 850 or anywhere around 1000 and see whether it will idle sooner for you. I bet it will.

Mr.Chewbacca

how do i adjust the idle?

My car's owner's manual (It's a '79) said that the Idle should be at 750rpm. Not sure if the S2s and S3s are different... Mine's startup procedure says to hold it at full choke (4000 rpm) for about 15 seconds. Then, drop it to 2000 rpm for about 2 min, then push the choke in all the way.

It's just part of owning a carb, you have a choke use it.
