Trouble with rebuild

(1/3) > >>

Landshark:
I just finished a carb rebuild to go on a Chevy BigBlock. I used 71 jets, 43b primary rods, AX secondary rods, set the float at 1/4 inch, new accelerator pump and a red power piston spring from Cliff. There are all recommended parts/settings for a 427. This is running a divorced choke. Bad news is it idles like crap. Fuel mixture is so rich that I can be in the garage for more that a little while since my eyes are burning so bad. and it smokes really bad, not oil, just unburnt fuel The idle mixture screws have no effect.  I am not an experienced rebuilder as some of you are, but I have been going through Cliff's book to get at least a good working knowledge of a Quadrajet. Any help/advise would be appreciated.

Thanks

I just swapped out a different seat .135 slotted. I had a solid .134 in. A minor change. Exhaust is still black and leave soot on floor and still now effect from the idle mixture screws.

carmantx:
What is the carb number?
What are your engine specs?  What cam?
Did you make changes to the idle circuits? 

Landshark:
The carb is a 7029201 which is a BigBlock carb, just not the number for my car. (709215)
I have a 69 Vette 427/390HP 4SP. I had the engine rebuilt a couple of years ago with the following info

CompCam Roller
.510/.510 lift
270/276 duration
112 lobe separation
They had to bore the block another .010 for a total of .040.
Power Forged Pistons
CompCams Magnum roller tip rockers
Resurfaced the heads, balanced the crank and flywheel, all new valves, guides and seats. New oil pump.

Did you get the rebuild kit from us, or just a few parts?.....Cliff
