i have 2 demon carbs on an offenhauser intake with edelbrock progressive linkage on a 454 chevy. when the car is in park it idles at 2000 rpm. when i put the car into gear (700r4) it wants to stall. i have tried to adjust the idle but that doesn't help when the car is in park. i do not have much experience tuning a set up like this so any help is greatly appreciated!!

I think the only way i'd do it is if one carb was totally closed at idle. I have set them up before and adjusted both carb seperately but one has to have the throttle blades totally shut. The demons with the adjustable air bleeds and the idle air inlets in the baseplates might be trouble. FRANK
