The Camit tach sensor was designed by Brian Anderson of New Zealand. It uses a small hall effect ic and some components.
I built one and use it on my Jab. Camit put it in a nice alum package and used them on their engines. I doubt they are
available now. If you want to make one, I can dig up the schematic and send it to you. -or- you could use a Honeywell gear
tooth sensor #32315204. It has been used successfully on a 3300 Jab by a Zenith builder named John Austin.
