    I mix oil with the gasoline.  However, the fuel in my tank has been
sitting there since I last flew in April.  I wouldn't think that the oil
would settle out of suspension over time and you would have thought that
flooding the chambers with gasoline would have left its own oil deposite on
the metal.    Since the engine has sat for months before without being run
without any problem and the only thing different this time was the severe
flooding I am inclined to think there is a connection.

  If only one or two apex seals had stuck I might have looked for another
cause.  But, in this case all the apex seals are failing to provide
compression.  There is not a single rotor face that gives that "PoP" of air
as it rotates past the exhaust.

  I plan on tearing the engine down and will report on what I find.

Ed, as I recall this engine was overheated quite some time ago to the point of
your having to replace the warped rear rotor housings. As I also recall this was 
caused by air being trapped in the water jacket due in part to inadequate 
water jacket venting in the plugs up position. Also you had an oil cooling 
problem for awhile. Did you replace the apex seal springs when you overhauled 
this engine? Sorry if this sounds like the third degree. I am just trying
to learn from this experience. 

Weak apex seal springs in conjunction with the rust or gum from the evaporated 
gasoline could have caused the apex seals to stick. Have you tried spraying 
an apex seal through the exhaust port with WD 40 and then trying to move it 
in or out?

I would also take a small sample of the gasoline and two cycle oil mix you use
and let it evaporate in a glass dish. Then try various solvents on the residue 
if any.
