can somebody tell me which is the intake side on the rotor? I need to know what apex seal to point down for tdc.

Thanks

If I understand your question correctly, I doesn't matter just pick one and make sure your within the running area of the side housing.

 

it doesnt matter what face of the rotor is where?

 

well, each face actually does intake, comperssion, ignition, and exhaust, so... my guess would be no.

if any of the faces were different, then it would cause problems (i think) , balance, different amount of power varying between faces, etc...

www.howstuffworks.com search for rotary engine. it will make things MUCH clearer for ya.
