Hello Steve,

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

Thanks,
Dave Williams

Thanks guys.

Dave, did your measure the timing with a timing light and with the prop =
on?
Must have been pretty windy getting that data!

I=E2=80=99ll 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.=20
And particularly anyone running a 4 port renesis like Tracy=E2=80=99s =
RV4.

Cheers

Steve
