I think 19-20 is normal. Mine is at 15 when I first start it, once it warms up it goes down to 20. :( I have a weird vacuum leak I guess.

anything from 18-23Hg is normal, although i found myself at around 18Hg until i tightened to boost line to the gauge and it started reading 22Hg. higher elevation will see lower Hg.

turning down the idle screw? is this something that i should be adjusting? I just dont want to adjust one thing to compensate for something else that is wrong. I want to get at the problem, not covering up the symptoms. But if adjusting the idle screw is the correction to my problem...then give me directions, please. thanks
