Here is a picture of what the adjustment looks like.

thanks ...
Yes, there's an altitude trim on my generator and setting it to max didn't help.
Code 36 seems to be indicative of a fuel problem however the plug had fuel on it when I pulled it and tried a new plug, also opened that drain screw below the trim knob to see fuel pour out (shortened story). Seemed like it wasn't getting spark because the sound was no different with plug connected or disconnected.

The odd thing is that it started and ran fine loaded and unloaded once we got back to the house. All seems normal and 7000' isn't too crazy high elevation however I noticed it's above the value printed on the trim knob.
