OK, so I just rebuilt my carbs and, as far as I can tell, they're back together the way that they should be. I trued every mating surface that I could reach, threw a rebuild kit into each and also replaced all six butterflies.
I can start the car but it feels like it has a vacuum leak the size of Montana. First, I have to idle it way up to keep it running. Second, the idle adjustment screws have absolutely no effect when turned...I can turn them all the way down with no difference. It smells rich but not too bad. Backfiring like crazy and turning the distributor has little effect...but i can advance it to the point where it dies.
Hmmmm
All the little vacuum hoses are where they're supposed to be. I'm taking PVC vacuum from the manifold, just below the center carb, on the passenger side.
Geez, with it running this bad, and if it were a vacuum leak, you'd think I'd hear it.
From what I can see, everything that should be is where it's supposed to be.
Maybe the secondary valve diaphragms are leaking?
Still, that's gotta be a BIG leak if it is one.
Any ideas?
Thanks
