Guys if you want you can go up to 34 BTDC in timing that will be an optimal timing.
Talking with manufacture any change from OEM SETTINGS will void the Warranty. This is all what I can say.
I have something similar coming out for for al radial engine, couple options , ring option and sensor .
Basically replace propdrive keep the sensor, keep propdrive replace the sensor.
But please keep in mind what I have been told from manufacture and that is their decision.
The 3rd option I could do next year will be to make a CDI that will take care of all internally , just replace the CDI and will be the 30BTDC.
Thanks
Adrian
