Hello all, I'm having a problem with the Q-Jet on my 75' Regal 350. The car sits a lot and I know that this is part of the problem but it has been very frustrating dealing with carburetor issues the past few years and because of this I often don't feel like driving the car. To give a background this is an 800 cfm Fred Catlin built carb. custom made for my engine. I bought it around 1992 and it sat in the box till I installed it on the engine quite a few years later. The engine is rebuilt with only a few thousand miles on it and it has the c118 Kenne, -Bell cam, T/A Stage 1 aluminum dual plane intake with 1" spacer, TH-350 trans and KB 2200 stall converter. The car runs very rich and the exhaust smells and burns your eyes. As I said the car sits a lot and the other day when I tried to start it up, the engine revved up to 2000 or more RPM's. I shut it off right away because I was afraid of that kind of speed on a cold engine. I figure it must have something to do with the choke which is the stock heat coil type with the exception of being heated by an aftermarket tube that attaches to the headers. I tried to adjust the choke screw but nothing seemed to happen and the idle speed screw isn't even contacting the throttle arm so I can't try to adjust it down. I disconnected the throttle cable and found that if I pushed the throttle arm slightly back from its seated position the idle speed did come down but only slightly. It wasn't till I started playing with the choke butterfly with my hands that the idle started to come down but then the engine was "choppy" and very rich. When the car is running properly it is a joy to drive. I just want to try what I can before I absolutely know I need a rebuild. I know I can always rely on all of your good advice so any help you can give is greatly appreciated. Mario.
