   Thanks for the heads up on the lubricity issue with AGE 85. In light
   of what
   you said it would be prudent for me to premix two cycle oil, especially
   since I will be going with the 10:1 Renesis rotors. One point I would
   appreciate your opinion on.  I am considering having the two or three
   injectors per rotor.

   I want to place an injector (probably the primary for better idling)
   in the
   location of the oil metering hole and the secondary injectors shooting
   through the P port after the slide throttle.

   Because of the size of the hole needed to provide a spray directly
   into the
   chamber won't that hole volume lower the compression ratio?  Ditto a
   third
   spark plug?

   Thanks

   Doug

Doug,
If you inject through the oil hole, or near the intake port, it won't
affect the
C/R much. The third plug would add some volume and would lower the C/R
some. A little at least. Three injectors for ethanol sounds like a good
idea.
