Subject: KR> vacuum

can the VW  motor develop vacuumed to run an attitude indicator?

Rick
The best thing to do that is easiest from all that I have seen, and still
keep it simple, is to buy the large vacuum venturi from Wicks or AS&S, that
will support both AI and DG. It can be mounted right under the plane, check
out Steve Jones' plane pictures for location, and eliminates the failure of
the drive shaft and the mounting hassle of the vacuum pump. VW's don't have
the drive for it, so you will have to use something similar to a ignition
mag drive, but turning the correct rpms. You will need to use a vacuum
regulator, but should find it ALOT easier to get installed and setup.
