Hi 36 sedan,

Carb gaskets are about 3 weeks old. After rebuilding there was no more whistle and that carb always had the same vacuum reading even new. Intake is Weiand dual plane with th Quadrajet base but I put a separator plate in to cover the bigger spacing in the back.

I did have the advace to ported vacuum before. The speed shop guy says my recurved weights will handle the timing at 23 degrees played out at 2000 rpm. He says I had too much total timing.
However, I think at this point is has to be carburetor lean as I think I beat the distributor horse to death. I will do all you suggested. Today in fact. Mrs Goodwrench says to switch carbs and see if the problem is still there. I'll recheck my gasket sandwich as well. I will need a new timing light however, some say they don't work with multispark ignitions, If not then what does?

Something I forgot to mention, In the distributor cap the burn marks are right at the front of the tabs, and clean afterwards. Is that normal?
Anyway, I'll look at the fuel and vacuum parts. Thanks!

Well, I went out and got the wd 40 ans started spraying all over that carb, base and intake manifold seams. Checked all hoses. Nothing. It popped twice through the exhaust. Otherwise ran like a striped ape. It's just got to be a vacuum leak somewhere.

11 degrees initial, 23 degrees mechanical all in at 2000, total is 34 degrees. Looks like a good curve, 34 total is ok with aluminum heads, iron heads may need couple degrees more. If you have iron heads bring your initial up 13-14 degrees, bringing your total to 36-38 the iron heads should like it better, if aluminum leave it where it's at. You can add 7-10 degrees vacuum advance to either and have a happy motor..
