I have a dom that the idle goes up when I turn the a/r screws vin. Last 3/4 turn. It only does it when its hot. It started doing this on my way back to the pits. Idling at 1800 rpm. When I turn the idle down hot and let it cool down I have to turn idle back up. Already spray starting fluid around carb base,int and metering blocks but to no avail no change. Pulled caeb cleaned and blew out. Changed bowl, metering block and carb base gaskets. Any ideas are greatly appreciated. By cool down I mean just down to 145-150 ish.
