The Rotax manuals say many things which sound mandatory, but in most cases are only factory recommendations for us E/AB people. Rotax does build certified engines and the rules are different for those.
well thanks again Jim - it's kind of tough trying to figure out a lot of this stuff so I am grateful to this online forum - it's been a lifesaver!
