Congratulations, Bill! Did you note the mixture monitor bar when you were at max static? A = turn of the mixture knob may get you some more RPM. 31.5" may be possible if you were at sea level on a cold day. I found = that I had to recalibrate the manifold pressure with a gauge to get the = correct reading. You pretty much need to check calibrations on all temp and pressure readout to assure accuracy - I least that was my experience. Al
