Sorry man. I whs I could help, but you are talking to a guy who did the same carb swap and left the vent cap unattached. Just put it filtered vent in there. I will check the PVC valve and see where that vacuum goes, as well as what is hooked up to the bowl vent - once I get the Jeep back from the tranny shop. Probably be either Friday or Monday. In the meantime, if I can fine that guy's cellie, I'll reply back with it. I didn't even hook up a choke - started it up in the NW NJ winters each morning by just keeping the throttle up while sitting in the driveway.
