Paul;  Jim Weir gave me the name of a fellow in Arizona by the name of
Gilbert who makes mixture controls for carburetors.  He used to advertise in
the Sport Aviation.  I believe Jim had one of these on his RV-6.  I haven't
checked this out yet as I'm still working primarily on my airframe.  Should
be getting to the fun stuff of getting the engine started next month  JohnD
