Magnet mount? Drill a hole in the prop hub and jb weld a magnet right into it. Your sensor ring will need to hold the sensor about a millimeter above the OD of the front engine case to align with the magnet in the prop hub. I haven't drawn one for that engine in fusion yet or I'd send a model. Feel free to share whatever you come up with. I could probably print and use a couple on my boxers and the geometry is probably the same for the os, the magnum, and the asp.

Obviously it was not "recently" bench run and it was also not run out or stored properly - Smell gave it away too.
Has been disassembled and every bearing is done - Badly corroded - No other issues as cam/crank/followers are all OK with only minimal slight staining and no pitting. Rods/Liners/Pistons/Rings and valve train all look 100%...
Questions:
Should the tiny rod cap bolts be replaced during build up - Thinking and reading this might be a good option. Locktite?
Any advice on bearing replacement (what to look for in bearings) - The seller has agreed to split of the cost of the bearing renewal - felt very bad about selling in this condition but he had bought it from a fellow modeller who passed along it was "MINT". I don't get the feeling he meant to mis-represent the motor but got caught passing on bad info. The bonus is that it will start its gasser life with fresh bearings.
