Dang.
I can't keep it there because of a common alternator, but in the summer, during the day, it is quite alright (the lights dim below 500 rpm)
it is a HUGE fuel save on the old carb.

I only got a quick read on specs typical throughout downdraft vac readings, (all cars) 22 inches HG is a maximum typical for gassers. I do not know what happens beyond that.

Getting too much could be as bad as not enough for the range of stoichial decency. 22 is the high end.
