CARTER BBD CARBURETOR VENTURI CLUSTER

Oct 19, 2006 6 Replies

Have a 88YJ with 4.2. Having problems with stalling, jeep will not idle. Took out idle tube and venturi cluster to clean them. Now I forget which way the venturi cluster is installed. With the domes up, the engine will not idle at all; with the domes down, the engine will idle but when braking the engine stalls. Any input?

Here is an exploded view of the BBD:

Stalling when hitting the brakes implies too low an idle or a sticky EGR valve. You can temporarily disconnect the EGR and block it's vacuum line to see if that helps.

There is a second bad idle situation, but that usually causes surges and pukes oil into the air filter.

Thanks Mike I had already looked at the link and can not tell what way the cluster goes. I guess what I need is a down the throat picture of a complete carb. I will take a look at the EGR

Well, the kit is about twenty bucks and you are right, it is a well spent twenty. Comes with directions and set up instructions.
