You first need to set the pilot screw adjustment so as to pull the correct level of Hg, this should then put your idle back to a factory setting, in your case the idle adjustment is probably set too high to compensate for a too low Hg setting at idle. Most including stealers have no idea how to balance carbs, its not just hook up the gauges and start adjusting. When they do it throws out the pilot idle adjustment, they compensate by adjusting the idle and this pushes it to the ends of it's adjustment, owners/stealers then start playing with the TPS and before you know it the whole lot is all over the place.
