    Are you sure you have looked up the correct specification for you engine....there are 2....and engine with an intake silencer and an engine without an intake silencer,

    Which engine have you and what carb set-up have you....also with or without intake silencer...and are you at sea level.

    If you look in the Rotax parts catalog which I think you can download free on the website goto page 9.3.1-7 you will find a very detailed jetting chat there.

    Which engine do you have and what alt is your airfield.

    Its under support on this site...here is the link,

    http://www.rotax-aircraft-engines.com/portaldata/5/dokus/d05246.pdf

    Its the parts manual you need to look at...that where you will find the jet sizes...look in section 9 under accessories....the chart doesn't give attitude correction,

    But be very careful you dont fit the wrong jets...with a 2 stroke this can lead to engine seizures due weak mixtures.
