Thanks Patrick. I assume you have "blank" 6-32 set screws or know where you got those from? Do you know the stock hole size? According to Gary I would need to just go smaller one size, which I take to mean # drill size.

And yes there "was" a bung, but I'm redoing the exhaust so right now there is nothing under there. I will put one back in, and yes, Gene mentions often of still having your wideband tool.

I just wish Holley gaskets didn't have glue on them. You can no longer pull them apart without using all new gaskets.

Also, though I think we debated this long ago, there were two screws missing in the base plate on this carburetor. I noted when pulling the secondary plate off the back side the large cavity behind those plates was fuel logged. The missing screws were just below this and the similar spot up in the front. These screw holes were also in the vacuum paths. So... I put some in. May have no bearing, but should have really plotted that out WIWAI.
