Heres the deal. I rebuilt the 305 and its now got bigger cam, ported 416's, etc. I was unsure of the carb before I did all this because it was giving me idle troubles, and acceleration issues but we all know that other things could affect this as well. This weekend was the first weekend that I got a chance to drive the car with the new engine. The choke isnt working correctly but once the motor warms up it idles ok in "P" but when you shift to "R" the car will eventually stall. I turned the throttle stop screw in a few turns to get a better idle to allow me to drive the car and sit at a stop without the car stalling on me. Thats one problem. The next would be acceleration. Sometime I can cram the gas peddle down the the floor and the car goes great and drives for awhile like a dream. Then other times out of the blue it will bog and its like the engine is starving for fuel. I get a good 5-6 PSI from the pump. I bought a rebuild kit today and was wondering if I'm barking up the right tree and how difficult is this carb to rebuild, and special tools needed, etc. The kit I got just looks like various gaskets, etc thats pretty easy to replace.

With these electnic carbs, the idle speed i controlled by the ECU and the idle speed "motor". There's a specific procedure to setting the idle; you should consult your service manual for specifics.

As far as rebuilding the carb, you need two special tools (that I can recall) to set the mixture control. The mixture control solenoid needs to have it's end points set (lean/rich).

As far as the bogging goes, make sure that the secondary metering butterflies are free and not hanging up. These are the butterflies that are at the top of the secondaries.

It's been a long time since I've had a Quadrajet apart. Taxes my memory banks.

Edit: Make sure that the accelerator pump is squirting. Look down the air horn (with the engine off) and make sure it squirts not only when the throttle is opened quickly, but that it squirts when the throttle is opened slowly too.

All good information, except that ThirdGens did not have an idle speed solenoid or control for other than A/C idle increase. Curb idle is curb idle on these cars.

The special tools are a 2mm "double D" for the lean mixture stop adjustment of the mixture control solenoid and the primary idle mixture control screws, a 2mm hex for TPS adjustment, a 7mm "double-D" for the main metering jets, and 10mm "double D" for the mixture control solenoid-rich screw. They are well worth the $15-20 you'll spend on them.

I think you are certainly at the right tree, or at least in the correct orchard. I'm guessing you have a mixture issue, among other possible problems.

Ok, help me out on the special tools, and in the event of sounding really dumb, whats a "double D"? And can I find these in a local auto parts store as this name?
