Wait, the floats I bought last year were absolutely the last redesign, never going to leak etc etc!! Makes me wonder how good the rest of my engine is when they can't make something as simple as these things.

I suppose its possible that the "new" floats are actually the ones I already have, otherwise I'll be on my third replacement in just two years, pretty crappy.

I know how you feel think it should be at there expense if they can’t get it right starting to get fed up with it .

My engine is not in the serial no. list. But I had to exchange the floats with SB-912-067. The new floats were marked with 2 dots. Does anyone know if this SB applies to me because I have no clue what part no. the floats with the dots have?

Hi Michel,

It appears your two dot floats must be replaced with the new floats marked with an “R”, please read this: https://www.rotax-owner.com/en/rotax-blog/item/71-rotax-carb-floats... 


Hi Jim, right on the spot. Thanks a lot.



I have been advised to give engine number to Rotax and they should cover replacement parts.

here in Australia will find out next week for sure.

Found this hope it helps
