Have a 700 Holley DP that sat for 6 months during an engine rebuild. I did drain all the gas out of it before storing it. The needle and seat stuck when I went to put it back on the new motor and I promptly replaced it.

From there we succesfully fired up the motor and eventually put approx. 15 miles on the motor.

Then, out of the blue the motor wouldn't idle. The motor runs fine over 2500-3000 RPM though.
After a lot of adjusting with the idle screws and float levels I gave up and put on a friend's 850 Holley (bone stock). Motor ran great and idled no problem (ran 109 MPH in the quarter mile with the 850). I figured a rebuild was in order for my 700 Holley at this point.

When through the carb using a Holley rebuild kit but really never found any thing suspecious. It was quite clean inside but I still make sure all the ports were unclogged by using compressed air.

Put the carb back on the motor only to find the same results before the rebuild. Now I'm thinking about having a Pro go through the carb. Any other ideas?

I've put a lot of time trying to get this carb to idle.
Between adjusting the float level, idle mixture screws, secondary butterfly setting and even tried drilling a 3/32 hole in the primary butterflies.]

I'm out of ideas at this point. Could something have warped?

Did you pay very close attention to the idle air bleeds at the top of the main body in the venturi area?

Alex,

That's a great thought.
I do remember cleaning them out, but I'm going to double check them.
