Was your carburetor built by someone who specializes in Q-Jet performance builds? If not you may want to consider sending it to one of a handful of guys that really know their stuff about Q-Jets. If you have a race prepped Q-Jet, the first place I would look to solve the high idle problem is look for vacuum leaks.

On another note, if your cylinder heads are ported, they are illegal to run in stock eliminator.

I have used Danny Ashley with very good results. The Q-Jet requires special prep with idle and off idle fuel, Danny knows what to do. Also, talk with Danny about "no rod jetting" Most racers run without primary metering rods. When you arrive at the correct set up for your engine, the idle will be good and the throttle response will be instant.

How much fuel pressure?
You might need to drill some holes through the primary butterflies to clean up the idle.

THANKS for the help.
Just a note, I'm using my bracket motor not a class motor yet, I was just trying the
Q-jet, to seeing if I could get it work.. The carb is near new off a 400 in a truck and has not been work over. I know a built carb will be needed, but I need a litte help from MR.GREEN ( $$). John
