Yvon,
Was your 13B freshly overhauled when you began flying and how many
hours in
the air currently..............Condition of the rotor side seals and
their "O" rings plus
side plate wear steps are the main controlling factors + the percentage
of 2 stroke
oil............As the engine rotor side seals, "O" rings and side plates
wear then more
of the 2 stroke oil will get past them and into the oil
sump...........

I have been using a ratio of 1:140 for
some time and still getting an increase in the oil pan. I do not run above
5500-5600 engine rpm. My engine is a 1986 13B. Yvon.

Just talked to John again. Engine emergency caused by
clogged fuel filters (John mentioned debris caused by some fuel tank work
of some sort?). Saw fuel pressure fluctuations on EM2 and increased
EGTs then rpm started falling. After landing, John found the
clogged filters & cleaned them out. That procedure called for
closing a shutoff valve from the tanks. After cleaning the filters,
he forgot to turn the shutoff valves back on, hence the failure to
start. He eventually noticed that fuel pressure was super low and
that eventually jogged the memory of the shutoff valves.
After opening them, the engine started immediately.
The RPM
anomaly is still a mystery & I didn't think to ask him if that was
back to normal. I'm sure we will hear more later. I'm kind of
amazed that the engine still had good compression after 50 gallons of fuel
with no oil added was used.
Just random thoughts: I'm
thinking I should cut back on the amount of oil I add. I'm still
accumulating 2 stroke in the crankcase when using 3/4 oz per gallon of
gas. Think I'll go to 1/2 oz / gal. on Renesis. Peripheral
exhaust port 13Bs need more oil than Renesis but 1 oz/gal is probably
overkill.

Called John to see if I could help. What a
saga! Lots of indications that it is clogged fuel system
somewhere but also some symptoms that occurred simultaneously that
make no sense at all (like a double rpm indication). John
says compression is good/normal in spite of two fuel stops with no oil
added to gas (forgot). Engine was running normal at shutdown
after emergency landing but now won't start. Unfortunately John
has none of the EC2 upgrades including ignition & injector
diagnostics and has not tried checking for spark while cranking since
that is a 2 man job. I forgot to ask if he had tried the
backup on EC2 controller but I assume he did.

Guys, I just got a call from John Slade. He had to
do an emergency landing in Graystone 17FL
(Ocala) FL. His engine will not start again, and
he needs someone with rotary experience to talk to. His cel # is
860-271-3941. Please give him a call if you can help in any
way.
