It has been a productive day!!!!
The ST2300 is installed, tanked, propped, and run in. HMOG. It will be truly unlimited, and that should be in caps. On the 10% PM fuel I broke it in on the std. muffler, with an APC 17 x 10N, and that was WAY under-propped. By the end of the first tank, it was singing, and I'm nowhere near leaned. The ST 2300 out of the box is just wonderful. Carburetor is perfect, and I'm running the Uniflow system, which seems to give it very consistent flow. High, low, in between. Oh, and the IDLE is just outstanding. I would fly it after this one tank, it's plenty good enough.

Pics of the ST in the nose attached. It really looks like it belongs there.
And no, I haven't checked the prop clearance, but it measures that there should be 5/8" clearance when the fuse is level with the stock wheels. Larger wheels may be all we'll need!!!!
