Was tinkering with the idle adjustments the other day. Set the idle mixture screws at best idle, and then played with the idle speed stop. I can completely remove the idle set screw and the car just sits there at 900 rpm. Should I back out the little, hard to get to set screw that holds the back butterflies slightly open? Have I said lately how much I hate my Holley carb?
The idle stop solenoid is not energized when I'm doing this. It is wired to the compressor engage switch.
OK, I backed off the back barrel set screw and now I can get it down below 800 rpm. Not sure if Holley would like that solution, but it worked. Holley says that screw should be backed out 1/2 a turn after it contacts the back barrel stops.Don't know where it is now in relation to that.
I was also able to turn the idle mixture screws in about 1/2 to 1 turn for best idle.
