Altimeter off

There's no adjustments on the encoder? I can set the altimeter on the
ground to the airport elevation, so I know it should be really close
to the correct altitude, but then ATC may see my altitude as being a
hundred feet off... The encoder never needs to be recalibrated? It
just sees what is at the static input?

Not legal, you'll screw it up. Even an A&P is not allowed
to "adjust" instruments internally. You should take it to a
certified repair shop if it won't pass a IFR check. The
encoder is factory set at 1013.2 mb/29.92 and there are no
field serviceable adjustments.

If the static systems is wrong, the altimeter system and
airspeed will also likely be wrong.
