Try turning the mixture screw on the carb out 1/4 turn at a time until you reach the highest idle point.------------------

Could it be the float level? Maybe fuel sloshing over from the vent? ALEX?

High float would make it idle very rough.------------------

heres another thing i noticed and i used your web site. when i backed out the idle mixture needle it didnt do anything until i pulled it out of the hole? so i put it back in and started the car then turned it in the most i could i think im going to invest in a vacuum gauge lol------------------

I thought the needle screw (item #49) only adjusted the idle mixture? Is the choke opening up all the way? Item #22 is the jet in that carb. At 3000rpm the idle circuit should not be the problem. But I dont work on anything under a 4 barrel carb either. If the same principles apply. Check the adjustment on the accelerator pump linkage and diaphragms. If they have to much slack it will stumble. Thats items #39 and #43. I see they have a screw to adjust them.
Let us know what you find.

ok i just looked at the accl pump linkage and it seems pretty taunt. one thing i did notice is when i go around turns now it tends to want to die unless i give it gas then its ok. also my idle is erratic. if i drive hard on it it goes up to about 950 rpm then if i flick the gas pedel with my foot it goes down again. if i drive like a lil bit** then the idle is fine. ------------------

Do this first and get the idle fixed. Adjust the idle mixture screw. Turning it in or clockwise, shuts down the fuel or leans it out. Backing it out, adds fuel or richens the mixture. To adjust, turn the screw in until the engine slows down. Then back it out until the engine slows down again. Finally, turn it back in once more until the engine runs the fastest. You are also looking for maximum vacuum at about 19 pounds. The screw is located on front passengers side of the carb.
I am going to ask. Are you using a stock fuel pump?? The going around turns sounds like a float too high problem. Is the carb a manual or electric choke??

hey 66coupei6 your website was amazing. i took my car to the shop when i firtst got it and they did the timing well it was way off when i read the vacuum line should be facing 6 spark plug and i saw mine was at the shock tower i was like ut oh. so i played with it and the real power of the msd came out holy crap. no more bogging runs better and i bet gas milage will be better since i had to turn the idle down wow. thanks for the info on your site it helped alot to ------------------
