I now have a real weight for a short block of my single rotor engine. It
 is 94lb as shown in the pictures. Should be under 150lb when complete
 later this week.

 Nice work Richard. I take it those are new castings.

Wow that is a really neat job, I assume the "front" flange is for
driving the accessories and the main drive will be from the flywheel
end? has it a heavy flywheel balanced for the single rotor? or you going
to use the auto flexplate with the auto balance?  looks a very good job.

Here are some additional old pictures for back ground info.

The power take off is through a ROTAX style 10:1 30MM taper. With this I have
a direct fit to the flex coupler of the Hirth redrive I am using.
The flywheel is only for balancing and and inertia. Also, the ring gear
with 100 teeth, is smaller than the one on the MAZDA, giving me a higher
crank speed for better starting, using the original RX7 starter motor. With
this set up I never had any starting problem except with my first engine
when it flooded, also had very worn out apex seals. Even with the present
engine, if it is flooded, closing the fuel and open the throttle solves the
problem immediately.
