Installed the showplanes bracket and temporarily rigged the prop cable. It took a bit of trial and error to find a routing for this cable that weaves through everything and still had the proper geometry by the time it gets to the governor. but ultimately I got something that works well.
I did have to reclock both the arm and the faceplate of the governor to get a geometry that works with no interference through its full range of motion.
I don't have. manual for that specific governor, so in taking the faceplate off, I broke the screws loose with a screwdriver bit in a socket in my torque wrench. They broke loose between 13-17"/lb so when I reassembled everything, I torqued them all to 15.
Governor is all done and safetied, with the stops set at approx the original throw positions, although I suspect they might have to change during engine runs.
The cable is trial fit, but not permanently attached to the governor because it will have to thread through a hole in the engine baffles one they're done.
