Quickfuel 750 starts, idles, revs good after drilling the throttle blades but rich at idle

Blades barely into the T - slot. 1/4 turn on idle speed screw.

I wanna lean out the idle feed restrictors 2.

This carb is way too small for this engine (462 BBC), I know. I should have put a BLP dominator on it.

What idle feed restrictors does this carb come with out of the box?

I spoke with em on the phone and FB, Quick Fuel saw the video on FB and told me the same thing Johnny at IRD and Mark at BLP did, the carb is way to small. That the engine would not perform to its potential 650hp. All signal no air.

When I bought the 750 carb, the engine was to be a 8:1 compression engine, with a Big Mutha Thumper hydraulic flat tappet cam, maybe 500hp.

I gave up on the idle feed restrictors, it'll have a pretty decent carb on it, comparatively speaking, by noon tomorrow. 950 cfm BDQ

Good choice going to 950
