I made the mounting plate for this test using my mill. This was yet another occasion when I wished I had a plasma cutter. It would have been so much faster making the cuts to clear the float and the starter bar linkages. I wasn't planning on keeping the plate (which I made from sheet metal scrap). Based on my results I think I need to keep this for possible future use!

Interesting test, you likely have solved your problem.
