Does the engine turn over smoothly? If so, put some fresh oil and coolant in it and try bumpstarting it in second gear at over 25 mph. You'd be surprised how many of these cars got junked because the apex seals carboned up and got stuck. They'd show zero compression and people would think they needed a $3000 engine rebuild. Bumpstarting over 25mph slings the seals back out. If the bumpstart gets it running, shoot a couple shots of ATF into each rotor through the spark plug hole, spin the crank once, shoot some more ATF, spin it again, shoot a little more, and then let it sit overnight. The next day, crank the engine with the plugs out (and no fuel delivery) until the ATF is out and then bumpstart it again. Keep the revs at about 2000 rpm for a few minutes until all the ATF burns away. It'll smoke out every mosquito within a square mile, but you'll be good for another couple years.
