I used a Douglas DG12-32 from 1992 to 1998, then replaced it even though
it was still OK.  My second DG12-32 installed in 1998 is still starting
the plane.   It has not leaked one drop of anything. My voltage
regulator is set to 14.3 volts.

It was really great to see so many beautiful Lancairs at Redmond.
