Previous threads on Rotax carb floats may have died of old age---I can't find them. I am again starting my annual condition inspection and would really like to try the Marvel-Schebler epoxy carb floats that the M-S website says directly replace Bing 861184 floats, which is what were in my engine when it was new. I have gone thru 861184, 861185, 861188, and 861189 floats in 4 years/290 hours and would like to get off that merry-go-round. Has anyone has RECENT experience with Marvel-Schebler floats? Van's builder support told me that they have not.
