Then (this is the part that most people dont do) use regular gas not premium gas. Look at your engine manual. A Rotax doesnt require premium fuel.Premium fuel burns slower than regular and is still burning as it exausts causing higher EGTs.Just try using regular with no other adjustments and see if it doesnt give you 50 to 75 degrees lower EGTs. Its so basic a thing that most guys dont do it but as I say after ten years of tinkering with these puppies using regular is an automatic for me..........hope it works for you.....Ill try to check back later on this blog to see if you have any comment on it.......don.addison@gmail.comAnonymoushttps://www.blogger.com/profile/12070097684395499785noreply@blogger.com
