I really like your T & TU instructions. They definitely save a lot of response time.
I'd like to offer a couple of additions, feel free to use or reject them.
Use Wet or Dry paper, it holds up well and does not shed too much. Try not too get any of the grit on the cam.
The point gap should be about equal to the thickness of a business card or match book cover.
Clean off the cam and wipe a little grease on it.
Shake the float and make sure there is no gas or water in it.
I'm not sure I like the wire brush bristle trick, I have wire brushes with bristles that are bigger than the hole in my main jet and they are very hard steel. I do like the soft copper wire though. I also like toothpicks but only if I can get to the other side of the jet to poke it back out if it breaks off!
I think blowing compressed air through a vacuum petcock may not be good for the diaphragm (sp?).
