Removed cowl to adjust the idle mixture again to further lean engine at idle.
Adjusted attitude indicator to level on the ground.
In flight, I could not trim sufficiently to fly hands off pattern speeds. I adjusted the trim tab servo rod (shortened) to increase nose up tab travel from 30 degrees to about 45.
The ELT activated again when transponder switched from ground to altitude reporting mode. I installed the battery in the ELT remote after landing.
