Bill got his RV done but then had some problems with his engine but I do
not know the details. I think Tracy can fill us in on this. What happened
to bill's engine Tracy?

Paul Lamar

Bill's engine is a long and tortuous story.  Much of it involves
instrumentation problems.  Readings showed engine very cool but all the
overtemp tell-tails that Bruce put on the engine showed that it was HOT.
 Trivia:  More space shuttle missions are scrubbed for instrumentation
problems than actual failures.)  Other problems with stuck seals, carbon
everywhere, low power, low compression, etc.  Part of the problem was traced
to crank angle sensor turned 90 degrees from proper position.  Quiz: Can you
figure out why the engine was able to run with this CAS adjustment?

Anyway, the engine was freshened up by Bruce and is back on the plane
awaiting tests.
