Having trouble with rht carby flooding when flying ,on the ground I  can get it stopped by removing the bowl and holding up the bracket then after I refit the bowl it seems good, the floats are good, 6 grams, float height is right, it’s starting to get dangerous, wondering what the the cost  would be to replace  both carb’s, anyone had this problem, engine is a 914 with 1800 hrs

    I’d verify the circlip position on the carb needle. They should be different from each other per the manual. After 1800 hours some of the parts could be just worn beyond service limits also.

    If they haven’t been overhauled then they need to be done.

    I would carefully inspect the tip of the float needle and the float valve seat. Also make sure that the float mechanism isn't rubbing on anything. Is it worth comparing the left & right carb mechanism side by side?

    Carbs are expensive, I once bought a secondhand on for about £200 (GBP).

    I would have thought that you could find out what is causing your problem on the ground. Could you connect up the carb to a pressurised source (0.4 bar) and test the float valve?

    Hello Australia! Did you comply with the recent float Service Bulletin?

    Sent both carby to our Rotax mechanic, told they need to be rebuilt so hopefully will be as good as new , he fits replacement seats along with everything else
