I assume TDC is the same as a regular 12A. If you have a stock style flywheel you can pull the inspection plate on the passenger side and there is a mark on the flywheel that shows top dead center.

also the front pully keyway will be at 9:00. This is true for all rotaries.

Nice. Was going to offer my (lack of) expert opinion but it sounds like you figured it out! What are you using to control ignition on that thing? And is it carbed or fuel injected if you don't mind me asking? I saw a cool blow through carb setup recently and it got my interests perked.
