It mentioned 23 degrees BTDC on number one on assembly. Said to align timing marks. Is this engine static timed only?Would someone please elaborate on this procedure. I do not get full rpm's and have a high egt. Would like to check timing and rule out that it is not retarded,which would cause both these conditions. BOB ________________________________ Message 2 _____________________________________ Time: 12:34:41 PM PST US Subject: JabiruEngine-List: Re: 2200 timing From: "jetboy" Bob, The mags are statically timed. Unlike the Rotax, they have no low rpm retard. Only adjustment is for magnet gap. High EGT sugggests you have lean mixture at full throttle. Make sure the float vent tube is connected to the air box and the carb is behaving correctly or look for head seal leaks or induction pipe leaks. Most of this is covered in Jaba Chat newsletter on the website.

There is no adjustment unless you reposition the magnetos. Full RPM will depend on the prop that you use. High egt is caused if the mixture is too lean and is unrelated to timing.

Adjust the carb. Even Rotax made a video about this. Cold weather verses very warm weather means leaner fuel air mix. -------- Roger Lee Tucson, Az.
