OK more info. I change spark plugs and now it runs again. I set the timing to 13-14 initial and 34 total and it comes on fast. The vacuum gauge I was using before was faulty and I have a new one. It reads 11"-12" now at idle. Funny thing is when I adjust the idle mixture screws nothing happens. I can turn them all the way in and the vacuum gauge doesn't move and the RPM doesn't vary. If I turn both in all the way the engine runs for about 20-30 seconds as RPMs drop slowly from 700 down to 300 then it dies. The throttle blades are almost closed and no fuel is coming out of the boosters at idle. I have the tech guy at Holley pretty confused. The power valve is good, I took it out and everything seems to be fine with it and it opens. It is rated at 6.5 I wanted to take it out for a drive, but it's getting late.

Anyone have these problems before?
