Yes indeed, Bernie.  Absolute certainty can certainly lead you away from
consideration of the elements actually causing the problem.  I believe
Bernie was referring to my "incident" where  I knew with absolute certainty
I had 3 gallons remaining in my tank (and that turned out to be absolutely
correct) - however, that knowledge led me to conclude that my fuel problem
(engine was sputtering and eventually died)  could not  be due to lack of
fuel.  It turns out a fuel line fitting in the tank had come loose
precluding the engine from using that last 3 gallons.  However, my knowledge
of fuel in that tank caused me to briefly consider and then discard the
proper corrective action - switching to the other tank - dummy!
I mean if lack of fuel was not the problem then switching tanks would not do
any good - of course that was the action I should have taken regardless.
Live and learn (if you live).

Subject: [FlyRotary] Oil leak at filter solved

> OK, Ed Anderson taught us that it what we are sure of, but is wrong that
can screw up your mind.  The remote filter is from Racing Beat and has 4
ports. 2 have oil lines and the other 2 have a temp and oil pressure sensor.
I have had 3 different people standing by the firewall when the system was
pressurised and are inches from the filter. They all agreed that it was
leaking between the filter and the mount. I had checked the #10 AN fittings
where the lines are attached, but did not check the probe fittings because
when they were installed they had the orange marker stuff showing that they
had not moved. Finally today I pulled the whole system and pressurised it
with air underwater. You can probably guess that it was the cottonpicking
temp fitting that was leaking because it had not been tightened before
putting the orange marker on. You can't beleive the hours and frustrations
this stupid thing that I knew was not the problem has cost me.

rich. The engine gets much smoother and will run down in the 12-15 inch
manifold pressure area when the primary injector is disabled. My plugs are
suetted (SP) up after 10-15 minute run. Not sure it is doing it on both
channels, will try to determine that tomorrow for Tracy to do some head
scratching whether he thinks it is the controller or the FI'ers.

that we can taxi and get the DAR in here. Last time he gave me 50 miles
around OBE because I told him I did not wish to go S or E. There is PBI
class C to south and the ocean to the east. This time I am going to ask for
50 miles around River Ranch. This will allow me to go to places like
Lakeland :>)
