Valve Ajustment

While I was at spurlings Fly In in October 2004 a fellow by the name of name Craig Kissock who hails from Austin Texas told me this unit and was kind enough to send me these pictures. It's a pretty neat little invention.  I can't remember if it was Craig himself or someone else that came up with it. I've no Idea what the Micro switch does or what triggers it but when I find out I will add the information here.
