If there is anything you don't understand (and there probably will be), please ask me and I will try to answer your questions.--There was a lot that I didn't understand when I started into this, and I think I have it pretty well figured out now.

A detail (doesn't need to be a dimensioned drawing) of the spring location/arrangement on the governor might be useful.
Good question, Marv---this should show it clearly--

I have added a few more drawings and saved everything as .pdf files in the "Downloads" section.

This is something I was thinking about last night, namely, how to put a bolt pattern in each end of a round cylinder when the two bolt patterns are offset at a 45 degree angle from each other. I came up with this answer as I was trying to drift off to sleep.

Well, actually it started about 15 minutes ago. I went over to see one of the companies that fabricate custom machinery for me this afternoon, and put a big whine on them about the high cost of aluminum, sob, sob. ---So being the great fellows that they are, and seeing as how I've put about $28,000 worth of work thru their shop this year so far, they let me go out back and launch a full scale raid on their "cut-off" bin. I came home with a big cardboard box full of about a zillion dollars worth of aluminum, and just started work on the cylinder.
