After reading some of the replies to your pleas I am inclined to go along
with the throttle problem. The cable , unless perfectly rigged can easily kink
when you want to apply more throttle. Result- one carb goes out of sync and
engine runs 'rough'.
One of the peculiarities of the Rotax is that you have to push the inner
cable through the outer, which is , basically , not a good idea as the cable is
not robust and has to be - as per manual - looped in a particular fahsion in
order to avoid kinking or just plain 'sticking'
Try this - new cables if necessary or a re routing initially.
