Calling all engine builder/tuners/skilled DIYers
I have put a thread over in the general Tech section about finding TDC that I am hoping will be very useful for a lot of people with a bit of input from some of the more skilled members and builders on here.
Please take a look and input any information you can.
From my personal point of view it would be great if someone has a 20B engine part built with a defined and known TDC and they can give me a degrees of rotation between the #1 rotor tip being in the centre of the small trailing plug hole and the front pulley lining up with TDC.
Thanks for looking.

Also, on an S5 anyways, you can get close to TDC by looking through the spark plug holes, and marking the pulley where you can see the apex seal in the trailing hole and the leading hole. In between those two marks should be ~TDC. I only know that this works on S5. Does not work on S4, dunno if it works on S6 or a 20B.
Also you could search.

Thanks for the feedback guy's this is the information that can be found searching and I think leaves to much margin of error. Eye lining a keyway at 9'oclock could be quite a long shot off I think.
Hence I devised above what I believe is a more accurate method that could be of real benefit to everyone. I am quite surprised people are not coming forward with some numbers or replies on this. it is to benefit everyone and the future generation of rotary owners!
Thank you
