based on the info above seems like this wont be your solution, but I recently had issues with my idle and I couldn't figure it out. I have a Lokar throttle cable that felt like it had slack but turns out that I had the smallest amount of pressure on the throttle and I loosed it up about 1/8th and my idle finally dropped until it rested on the idle screw. I've had no issues with idle since... now I only need to tune the rest of the carb
