Now I stopped trying to remove it before I broke it, which is the good thing.  the question is - how do you remove the switch/air cylinder assembly from the governor?  I did the obvious - loosened the lock nut, but the switch body hits the governor housing so it won't rotate to unscrew out.  What do I do next?  the book implies you can disassemble it, but doesn't say how you go about it...

figured it out...  The line drawings in the book make sense after you take it apart, and if you finally realize that there is another picture on the other page that you have to look at as well...

I knew you figure that out pretty simple huh  lol but I still haven't figured out why you want to remove the switch from the cylinder to remove the assembly, I just break both lock nuts and unscrew it by turning the shaft that is the way you will have to do to adjust it fwiw 

good luck

Hey Clifford, you would be amazed at how tender I get on things when they cost the legendary $700...  there is no reason to remove the switch from the assembly unless you haven't figured out that the 3/4" nut up by the housing is a lock nut that lets the switch body swivel so you can unscrew the long threaded bit out of the governor body.  I hadn't figured that out...  and I didn't until the switch et al was on my bench in two pieces.  I put it back together again.  Good to see how it works anyway.  The book says that as long as you don't actually take the switch apart it doesn't lose it's adjustment.

I guess I'm getting along on this project if I am fussing with fast idle switches...  I am also about to clean and replace all the little plumbing bits.  I finished the exhaust manifold, intake manifold and turbo install on the weekend.  I used several new vee-band clamp assemblies  so that the manifold can be removed/installed in several pieces.  I'll take some pictures when I get my camera back next week.  I bought the bends and vee-band assemblies from these guys, I used a lot of their stuff when I was building race car headers.  Absolutely top drawer.
