Hey all, here again with another engine problem. I know nothing about engines really, but recently swapped my carter 2BBL and intake over to a Holley Street Dominator intake and Holley 4160. Now, I rebuilt the Holley because it was NOS from the '70s and put new intake manifold gaskets, the metal ones. It was fine for a bit, but lately it wont idle in gear. Park, Neutral, just fine. The minute it goes into gear, boom dead. Instantly, can't even keep it running. So I tried adjusting screws and timing and what not, it didn't help. I decided to smother the carb, and the RPM shot up. Okay, so I sprayed the base of the carb and where the intake meets the heads with brake clean, revs up doing that too. Can I seriously have a vacuum leak coming from everything after no issues for a couple days?
