I've searched around the forum and couldn't find anything related to this (maybe I didn't look hard enough?), but where do you adjust the idle? When I start the car it stays around 500 and if i hit the gas it dies (i have to pull the choke out until it stays around 1200 for a bit)

Someone just posted a picture in another thread with the screws labeled, about a week ago. I don't know remember which thread, but you should be able to find it.

If the engine is cold, are you using the choke at all? Or just trying to drive?

dingo

Yeah, I only use the choke when the engine is cold, after I drive around a bit and let everything warm up, it seems to be fine, but it still idles so low i'd like to try and turn it up... I think I saw the picture you are talking about, it's the yellow and red screw on the blue carb right?

Narcisse91

Yeah, there was a yellow and red screw. Can't remember the color of the carb. One is idle and one is mixture.

You talking about this image? I tried to find these but couldn't.... i guess i have to take the blue air filter box off?

Hey ... Don't tear things apart yet!! Using the above picture.....you'll be lookin' at the carb form the drivers front fender....
Your gonna need an extra long ( I use an 18" #2 phillips ) screwdriver to get down to the screws.

The red one in the center of the base plate is mixture.....and I've found is VERY sensitive to adjustment. ( Although I just figured out today my shutter valve is in the toilet...aka big vacuum leak )....so turn it very carefully.

The Idle speed is the other phillips head tan screw....and it is buried. You gotta go past vacuum tubing and hoses, etc....but once you find them it's easy.

Good Luck

hahahaha, well a good place to start is go all the way in. then turn it out around 3 - 3 1/2 notches. for me that was kinda rich, but a good starting point! lol, it's true that LEANER IS MEANER all motor, but be careful! hahaha WOOOOOWEEEEEEEE!

that picture is wierd, anyone else notice the carb is on the manifold backwards??


You might have to poke thru the rats nest to see the screws, and the idle one might have a plastic comver on it..

Thats a SA carb, the later ones, like y 83 is different, the idle speed screw is towards the back hidden by that plate that secures the throttle cable. I wish it was like the SA carb, looks like its much easier to get to.
