Lynn, et al,

After putting my 13B back together and finding low compression and EGT on one rotor, and reluctance to start initially, I finally have a good running engine.

Something was obviously not right with that rotor, so I bit the bullet, tore it down again, and one problem was obvious as soon as I removed the rear iron.  One of the corner seal buttons was laying down flat in the hole.  SOMEBODY had managed to put it together without the spring behind it!

It now runs stronger than it ever has (it now has 9.7-1 rotors).  Turns out the low EGT was due to a failed probe, as it still only reads 200 degrees.  Never did find the coolant leak, but it is gone now.

Thanks to all who offered advice.  Hope to see many of you at the Austin Rotary Fly-In.
