Subject: [FlyRotary] Another mixed day
out at the hangar
Made it out to the hangar
for most the day and decided to take the advice here and modify my start up
routine based on what was suggested here and in the manual. So, I
cranked the mixture full rich with no priming and it started up in a few
blades. Ran for a while, shut down and started back up with mixture in
about the 2:00 oclock position....and it started fine.

The first bad news is that I replaced my
romote oil filter mount and installed a new filter. As I have mentioned
here I have had it leaking at the rubber filter seal. The old one looked
ok, but since replacing the filters no less than three times and knowing
that the eye cannot see all inperfections, I replaced the mount AND filter
(K&N 2004 filter). But, NO JOY. It is still leaking where the filter
mounts. It IS seeping from the filter seal and NOT the two hose
connections...no doubt on this. I know the rotary's oil pressure is
higher than other engines but I would not think it would be so much that it is
overwhelming this standard mount and seal. This is just a standard screw
on remote oil mount made out of AL...Made in the USA. Looks like many
others I have seen. Y'all have any ideas.
Second good thing is a guy from a few
hangars down turns out to be a welder by trade. He came down as I was
working on the new stainless turbo exhaust manifold the other day after
offering to help me modify my manifold.. As was mentioned here before,
the old cast iron manifold I had wold work if mounted upside down. It
puts the turbo lower (the oil return being about 2 inches higher than the oil
inlet return in the pan) to the rear of the engine and it clears my aileron
control link. I will have to make a very small modification to the lower
cowl to give me proper clearance EXCEPT the wastegate interfeared with the
Mistral intake fuel rail. So, I ordered a stainless copy of the cast
iron one I had, based on John Slades suggestion. My welder friend said
it would not be too big a job to turn the wastgate extension around which
should allow it to miss the fuel rail completly. We looked at the
options and he took the manifold with him saying he would cut off the old
wastgate extention and come back to fit the new part on in a few days.

The second bad news is that I was
doing some continued tuning. I even transferred A to B as B was a bit
rough from the factory and it worked fine. HOWEVER, later in the day,
after feeling pretty good about the lasted progress (excepting the continued
leak) the engine stopped. Huh? It will not restart. I checke the
first fuel filter and it is clear. I decided to start at the beginning
and just run the EC2's diagnostice test. Damn, no chattering of the
injectors (even though I was able to hear an individual click when I primed
it). Put on a test plug and wire and got no spark. All the
other electrics are working fine.
I pulled my extra EC2 out and
installed it and I got injector clattering away and spark on three of the
inectors. The secondary on Rotor one did not seem to fire.
Hmmmmm? I put on an extra injector that I had and tried again, and it
didn't fire...then fired for a few seconds and then stopped. Looks like I have
some more wire issues. Damn, I though I had really gotten past most of
those.
I am really confused about the EC2
seeming to just shut down. The other electrical componants are all
working, but the EC2 componants are not. Strange since I thought each
items (injectors and coils) had there own power source thus should not shut
down as a "team" like this. Yes, it is the same on A and B.
Currently I am very discouraged so I stopped for the night and decided to
crawl into bed with a hot blond and sulk (she was actually gracious enough to
hang out in the hangar with me for a few hours...whata gal)....well, she helps
me from sulking too much.....this dating in my 40's ain't all that bad
<g>
I anxiously wait commentary and
possible explanations from y'all. Upon my return to the hangar (today
was MY Sunday) hopefully tomorrow night after work I will be looking at
my, apparntly piss poor, wiring.
As always my friends,
Thanks.
All the best,
Chris Barber
