        Ken was going to build up an engine with them but then he got
        shipped off to South East Asia. Are you back yet Ken?

        Other than the idle I think it has few advantage for an aircraft
        engine as they mostly run from 5000 to 7500 RPM. A simple P-port
        would give the same or better power.

        Hi Paul,

        No,  I am still in Thailand but I am coming home to attend Tracy
and Laura's Flyin.  I sent the variable PP to Jerry Hey to experiment
with because I just don't know when I will be able to get my RV-4 (or my
Minimax for that matter) flying.  Hopefully Jerry will be able to make
some tests after he gets some of his present projects complete (boy,
does he have a lot on his plate!).  Due to my job situation  I don't
know when I will get time to make serious progress on  my airplane
projects.  Maybe sometime next spring.
