More taxi tests/oil leak detection. Leak seems to be at internal mating of starter components. Confirmed next course of action with Bill, removed top cowl and starter. Disassembled starter and noted metal-to-metal contact at joint where leaks appear to be emanating from. Probably was a gasket there that got lost along the way. Since parts not available from Sky-tec/Hartzell I went to town and bought gasket material, made a gasket, and reassembled starter.
Checked trim control operations, found travel is not as specified in TCDS.
