Right side running hotter than left could be caused by a number of things.
Nozzles are not designed or tested for low pressure flow, so it may even drop a couple of nozzles with the handled pulled out. Butterfly settings and intake reversion can also play a part. The nozzles are aerated, so they pull in air even if they aren't dropping the proper amount of fuel.
There is no exact setting for the butterflies and barrel valve, it varies with each combination. It's a little back and forth game, find the butterfly opening that gives the correct idle speed, then find the correct barrel valve setting that gives the proper amount of fuel at idle so it goes up on the converter clean. I set up at 2 flats rich from a clean hit on the transbrake, which happens to be 22%. .002 on the butterflies, idle out of gear at 1150, 1000 in gear.
The drop in vacuum could easily be caused by the oil being stripped from the vanes in the pump. I have found it best to drop a couple of ounces of oil in the pump before I fire the car for the first time that day.
Try not pulling the handle out so much.
