I have had to let my plane
set in the
hangar for about 6 months due to some family
problems. Today I pulled it
out and cranked it up with the intention of making
a flight.
I encountered several
problems.
- the
mixture graph on the EM-2 rose to the top and
stayed there. The engine would respond to
changes in the mixture knob on the EC-2, but not
the graph. I suspect that the O2 sensor has
failed. Is this max out of the graph a symptom
of O2 failure?
- the
oil pressure was fluctuating rapidly between 20
and 70 for quite some time after the start.
Could this be just the fact that all the oil had
drained during the shut down? I had checked the
oil level yesterday and it was down about a half
quart, so plenty of oil. It seemed to settle
down somewhat after the plane warmed up. OAT
was 68 F.
- the
fuel pressure was also fluctuating between the
teens and 45. I don’t know what the real
pressure was but plan to try and check it with a
mechanical gage tomorrow.
- oh
and the strobe quit working as well. When I
turned the master on to check fuel level, I
noticed the strobe didn’t work. I flipped the
switch a couple of times and the strobe made
about 6 or 7 strobes, then quit for good.
Maybe all these things are
related?
