Power Brakes Vac Pump

.....tried to tell ya man... a mild motor likes yours sounds should have plenty of vacuum.

Bet your carb issues disappear now too lol

Like I said... mild it isn't. The previous owner did quite a bit to it. My vac gauge is showing about 18", so it's not quite where it would normally be but it's enough to work the brakes.

Ha! That'll be the day! The first problem I had with that Edelbrock, and I suspect the last one the previous owner had, was the damn thing flooding after you shut the engine off. It stopped doing it after I readjusted the floats last week, and was running great, and then Sunday afternoon it started flooding again. Once again I have to hold the pedal to the floor to get the engine to start.

Check the float you didn't replace then check the one you replaced.

Phonelic(sp) carb spacer might help the carb from not percolating after shut down

Already have one on. I was told it makes a difference but it doesn't. The only thing I've seen make a difference is float adjustment, but I'm guessing the floats have a tough time maintaining position as all that regulates them is a thin strip of metal that's going to flex as it heats and cools. I think a better design would be to make the supports out of a non-thermal inductive plastic. They wouldn't be adjustable, but someone who does want something other than the stock setting could go with the metal ones and suffer the problems.

Totally different problem. With the bad float the engine would run fine for about 10 seconds and then sputter and die as gas came out of the top of the carb.

Once again, making assumptions that have no basis in fact. AFB style carburetors (and several other brands) have been using the brass floats for decades. There is no reason to screw with the float adjustment once you set it correctly. There are a myriad of reasons why you might be having these problems, but the design of the floats is not one of them.
