Hello Steve, I used the stock timing marks with a timing light. My timing light has an advance\retard feature. Yes very windy!!!

Dave, did your measure the timing with a timing light and with the prop on? Must have been pretty windy getting that data! I’ll mark up the ring gear with a TDC mark this morning and measure the current EC2 base Mode timing Which method do people prefer to get TDC? I think I have read about these 3 methods. 1. Rotor #1 equal Screwdriver depth to rotor face through both plug holes 2. Rotor #1 volume null using water in a tube - I think this might be from Lynn H 3. Rotor #2 bisecting Apex seal across T & L spark plug hole Can anyone else tell us their nominal timing at idle. Ours is ~1800rpm. And particularly anyone running a 4 port renesis like Tracy’s RV4.

You are on the right track because retarded timing will raise exhaust temperature. I have a 13b with Tracy's EC2\EM2 and the RD-1AB redrive.

I have a Renesis engine and Tracy’s EC2. In his A8 (Renesis) version of the handbook under Mode#8 Timing Adjustment it says to refer to ‘Initial Timing Adjustment’, however I can’t find any such instructions in this version, probably because it has a fixed position CAS. Can anyone enlighten me on what the static timing should at a given idle rpm? Much appreciated.
