Timing adjustment?

Postby DrGonzo » Sat Mar 12, 2016 9:07 pm

I see much printed about checking the timing on the Rotax but nothing on adjusting it. Is there any adjustment? If so what is the procedure? I checked mine and it appears to advance a little too much.

Thanks but I am talking about ignition timing, not cam timing.
