Frank/Tom & all, Thanks for the response about this issue. I took your sound advice and put a PCV valve back into the intake and ran it to the PCV port on the Holley. I ran the fill tube cap vent back to the air cleaner. All is well now. Started it up and after the choke disengaged, the idle was back down to "normal". NO hesitations at idle, curb idle or cruising around the neighborhood. Thanks again ... you guys are top rate in helping out! Sincerely, Greg Taylor :) <>< "And the testimony is this, that God has given us eternal life, and this life is in His Son.

Yes, you've created a vacuum leak! The PCV valve keeps the carb from pushing stuff back into the block (it's a one-way valve) but also restricts just how much can be sucked into the engine. Just get an in-line PCV valve and stick it in the hose. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list ____________________________________________________________________________________ Choose the right car based on your needs.
