Carburetor Floats

I've lost count of how many I've replaced in flying my machine 2,700 hrs.  No doubt thousands of dollars worth!  Anyone making the claim this isn't a significant problem is delusional...or trying to put lipstick on a pig.

Another symptom, in addition to rough idling is flooding on start-up--after a hot engine has been sitting for a few minutes in hot weather.  I just went through this and fixed it with new floats.  The two old ones were overweight.

Hi All reading the December 2020 carb float notice I see the floats marked 'B' need to be replaced.  done the bottom of page it looks like they may be ok in service if pass the weight test.   

I have ordered new 'R' floats and should get them tomorrow or next week.  The replacement service finished in December 2021.  Bugger I didn't find this out until a week ago.  My engine is a 912 ULS2  100hp with 301 hours TTIS.

Just keen tom know if the 'B' ones are ok still to use if don't sink.

Thanks in advance.
