Hence, the statement, "All measurements in degrees down; i.e., down thrust angle." I understand all of that, but you still didn't answer my question: where specifically on the engine did you locate the level? Crankshaft flange? Top of engine case?

When I say, "All measurements in degrees down; i.e., down thrust angle." I mean the down thrust angle from 0 degrees. (if you wish, Google 'down thrust angle' for a more complete description including pictures on some web sites.)
