Edelbrock carb question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

OK, I finally got tired of my Q-jet staying screwed up all the time so I installed a new 1406 Edelbrock carb on my 305 in my 86 GMC. It runs alot better, but I don't have a good idle. I'm still using the stock air cleaner and stock intake with a carb adapter. The ESC system has been disconnected from the stock distributor and the A and C wires have been looped. I'm gonna try readjusting the A/F mixture screws and playing with idle speed adjustments. I might even try flipping the air cleaner lid over to see if it helps.

Can anyone with experience with this help me? Am I gonna have to use an open filter air cleaner setup? Do I need to swap to a regular distributor?

Any help will be greatly appreciated.
