Yvon,
  Was your 13B freshly overhauled when you began flying and how m= any hours in
the air currently..............Condition of the rotor side seals and t= heir "O" rings plus
side plate wear steps are the main controlling factors + the percentag= e of 2 stroke
oil............As the engine rotor side seals, "O" rings and side plat= es wear then more
of the 2 stroke oil will get past them and into the oil sump..........= .

Just talked to John again.  Engine emergency caused by = clogged fuel filters (John mentioned debris caused by some fuel tank work o= f some sort?).   Saw fuel pressure fluctuations on EM2 and increased E= GTs then rpm started falling.   After landing, John found the clogged = filters & cleaned them out.  That procedure called for closing a s= hutoff valve from the tanks.  After cleaning the filters, he forgot to= turn the shutoff valves back on, hence the failure to start.  He even= tually noticed that fuel pressure was super low and that eventually jogged = the memory of the shutoff valves.    After opening them, the engi= ne started immediately. 

The RPM anomaly is still a mystery &a= mp; 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 g= ood compression after 50 gallons of fuel with no oil added was used.
