Al, are you saying you are only getting 5300 RPM with Wide Open Throttle?
If so, why so few rpms?
If you are saying that you were at 5300 ft., what are you doing there with only 2 gallons of fuel?
Ben

One other comment while it is on my mind.  I have run my 20B at 5300 WOT, gravity feeding from one main with about 2 gallons in it, through a 3/8”line; and the low level warning near the top of the sump did not come on.  From that I infer that even with only about 3” head above the top of the sump, I had adequate flow; maybe 18 -20 gph (EM2 flow flow not yet calibrated.  Normal operation then, with both tanks connected, I would have more than double the necessary gravity flow needed to feed from the mains to the sump.
