I am going to copy your starter mounting system.  It really makes since for me using a James cowl with the shark intake under the spinner.  I need the starter moves from the bottom of the engine to the side.  Do you have any words of wisdom as to how to determine the starter position to get the correct starter gear to ring gear mesh?

All I can recall is doing a lot of very careful measurements.  As you know, you need the engine shaft center to starter shaft center to be the same as it would be in the original position.  Be careful because I seem to recall that I determined that either the starter shaft centerline is not in the center of the hole in the plate for the ‘nose’ of the starter housing, and/or that the center of the starter shaft is not exactly on a line connecting the two starter mounting bolts.

 

I measured everything as carefully as possible; then center-punched where the new hole in the plate needed to be, and had a machinist friend put in the hole.  I drilled the new hole in the starter mounting flange myself.  Things lined up very well.  If need be, you can oversize the new mounting hole a bit so you can adjust the mesh before tightening down the bolts.

 

Good luck,
