Maybe the engine driven fuel
pump is failing. We are running low boost continuously in case the
engine pump fails and to address fuel pressure issues at altitude, hot
fuel, vapor lock and other problems.
I understand the engine will not
make full power on low boost (reduce manifold pressure and settle for
less power?)
Or, it might quit if high boost
is on and the mixture is not adjusted.
Since engine driven pump
failure, heat and altitude all affect fuel delivery, it would seem using
the low boost continuously could solve or make these problems
manageable.
Dr. Lyle Koen did our last two
physicals. He was a very likeable guy who built one of the early
IV’s and had over 1000 hours on it. We talked to him about joining
LOBO and coming to the Branson Fly-In.
Given the more knowledgeable
than usual witness account, could training have changed this
outcome?
