Hi, my name is George Crawford. I own an 81 firebird formula that i recently dropped a rebuilt 79 pontiac 400 in. It ran fine for awhile then i put an edelbrock performer intake and 750 edelbrock carb on it. It ran great for a couple months then the weather cooled down and it has run like shit. When i try to start it it overloads on fuel and floods and when i do get it going it runs real ruff and dies if i don't turn the fast idle way up to keep it idling. I checked the floats for sticking and they seem to be fine. (The carb and intake are brand new with only about 100 miles on them.) I installed an in-line fuel filter because i thought that might be the problem but it still won't run right and the air filter isn't clogged. I even backed off the idle screws to make it run leaner and it didn't help. Besides the intake and carb everything else is stock. Please let me know if you have any solutions...I can't figure it out.
