I grant, Eliacim, that Standard Day conditions vs. what you had west of
DFW the day you measured may not be similar.
However, by "engine was not producing full power" do you mean "like it
did before" or "not enough power?" The latter has been a complaint of
Ercoupe owners for years (like since 1946).
Things to check are throttle actually opens the butterfly in your carb
up full, and carb heat cuts off the hot air completely.

Well, as a begginer, the concept of static RPM is new to me. However, I
can say that for sure, without any doubt whatsoever, my engine was not
producing full power.
