Theoretically, the Stromberg is supposed to self-compensate for altitudes up to around 5000. But nothing is perfect. Certainly at 4000 it has to be less effective at doing so than at 2000. Absent an EGT or maybe even an engine analyzer and a nice fine vernier, I bet it would be a bear to find that other 50 RPM, though.
