 Do you pre-mix the oil and fuel Ken?

 Chris Cosman

   Yes but the seizure is from the rotor expanding and jamming into
the side housings as the rotor is oil cooled.

   Ken

I kind of doubt that Ken. Rotor is cast iron and does not expand much with temp.
The rotor clearance actually increases when the engine warms up due to
the aluminum rotor housings. I also remember you telling us about how
you taper the rotors in the lathe to give more wobble clearance.

I think bearing failure without oil would happen long before that.
I could be wrong. Did you take the engine apart and see evidence of this?
