Another Weber 32/36 Question

Hey Jeep pro's I know there is thread after thread out here about the weber 32/36 install and troubleshooting but Im not finding the answers I need.

So I am replacing the carter carb on my 89 YJ 4.2 with a used weber 32/36 I had on the shelf. I have had a few of these carbs on past jeeps but its been a while. Ive rebuilt this one and all looks well there.

Problem is I cant keep the jeep running off of the fast idle circuit to tune. As soon as I tap the gas to cycle down it stalls right out. I know the base line settings are 2 turns out on the mix screw and max 1 1/2 on the idle. What is the proceedure to set the fast idle screw at for the inital tune if there is one? I havent found anything about setting it. Does this have to be set before the the mix or idle screws? Looks like the fast idle cam adjustment affects the regular idle if Im looking at this right.

I am running manifold vacuum and have also replaced all the vacuum lines, so there shouldnt be any vacuum leaks and assuming I ran the lines right. Any other things I should check?

Thanks

Thanks, for the tuning document. I had I had pretty good notes written down but didnt have the actual directions. Pretty sure I follwed that to a T. I just couldnt remember if the fast idle circuit was supposed to be backed off completely or if made a difference even with the butterflies open for the tuning, They dont mention it so I guess it doesnt. Do you know if there is another instruction sheet for the fast idle circuit /electric choke. Might be my computer but I was only able to pull up the first page of the tech document on Redlines site. I called tech but im out of warranty.

Ill have to look at the carb and engine further to see if I have a linkage bind or vacuum leak somewhere that I may have missed and is preventing it from staying running.

thanks again!

Are you getting the proper fuel level/pressure?


From my experience they are more sensitive to fuel pressure than some other carbs.
