Bill, thanks.... both egts are the same. What I did notice though if it helps diagnose the problem, is the last inch of throttle does not increase the rpm at all. In other words..whether I push the trottle 80% in or firewall it...makes no difference...still only get 6000 max.
I was hoping to get a Rotax mechanic to service it...but he had a short stay in hospital which has slowed things down a bit as work has backed up for him. He is not even answering emails at present. So, even though O have never messed with these engines befpre, I may give it a try and check the needle as Ian suggested, and a compression check as Bill said. By the way, what is the best way to compression test? I heard online soomewhere you cant use the normal tester for these rotax 2 stroke engines.... is that right?
Mike
