I have been having fits after installing a new motor and Weber 32/36 Carb conversion from JCWhitney. I can't seem to get it to run right no matter what I do and there are SO many opinions on how to hook up vacuum advance. Red Line told me to use the ported (EGR) valve on the carb, and to cap the other vacuum port, but I've heard from others that Weber says to NOT use the vacuum advance at all and run the timing up to 12 DBTDC. My Jeep has no smog parts except the charcoal canister. The EGR is capped and will be coming out when I can find a plate for the manifold. There is a 3/8" ID vacuum line coming from what looks to be the bowl vent high on the front of the carb base, going to the charcoal canister. The disk shaped Valve(?) on the vent to the far right on the canister seems to be missing it's top. Today, I disconnected the bowl vent line from the canister to the carb, and the engine perked up with air coming in. Is this normal? If I plug it, I'm right back to rough idle. Can I run a line into the air cleaner assembly feeding this vent, or am I just loosing my mind here? PLEASE somebody help. I'm just learning, but nothing I do seems to work!!!!
