Wind was up a bit, so didn't fly. Switched out the right side baffle plate for the next taller one to balance the temps. Noticed oil under the heads of the #1 and #3 cylinders - will need to see what that's about. Disassembled the aileron pushrods from the control sticks to add a washer at the spherical bearing on each one. The control triangles were too wide for the spherical bearing, but a regular -10 washer was too thick. Located some of the thin ones and put those in. Also tightened the left stick to the control triangle. Installed the GPS. A prospective builder met me at the hangar and we talked about Sonex construction.
