hey mark my slots are showing about .015 the mixture screws are out 1 turn. i have 78-86 in it now and when i turn the mixture screw in the idle increases. but does not die when i turn it out to half turn it still has a lean stumble apon acceleration i go out to 1 turn and its so damn fat it loads up in about 2 minutes. im thinking the idle feed jets are to big in the blocks . i have 1/8 inch holes drilled in the throttle blades, i had the car running last night and farted around with it i just cant figure it out. i called pat at pro systems and im going to send him the carb next week ive had just about enough with it. nothin like spending 1100. bucks on a carb and it just being a pos. i should have bought a holley hp ultra but i didnt call me a dumb ass. thanks guys i appreiciate everything.
