power loss in flight

    After two flights of an hour (ovr the airport) with a few touch n gos, and no issues. Then the third flight, after 20+ min of flying and a touch n go, during a slow climb out, had a hiccup. Not a total power loss as before, but still an issue to be solved. So, checked the other carb floats and found one floating obviiusly higher than the other. Believe the floats are all original (2006 finished i 2009)

    Here's the question, have three floats weighing right at 3 grams and one at 4 grams. So the pilot side carb floats weigh right at 7 grams.                                 Do I buy one new float ? or both for the one carb ? or four floats ?

    Are the current new floats still of questionable quality ? The more research I do the more horror stories I'm finding relating to the inferior float situation. 

    Is there a choice of floats ? 

    As always thanks for any advice

    Are you saying three floats each weigh exactly 3.0 grams, and one weighs exactly 4.0 grams??  That seems SO unlikely.  If your scale is not accurate to tenths of a gram, you could have three floats weighing 3.4 and the last weighing 4.4 and you would be way (weigh) over (and not know it).

    3 floats are 2.9-3.2, 4th float was 4.1 then down to 3.9 after drying out a bit. As soon as removed bowl, you could see that the floats were different heights.

    Then I would get one new pair of floats.  They come in pairs, not singly.  You can reasonably replace just the 4+ one and keep a spare on hand for next time.

    Orderered four floats (apperantly made of gold $$$) and hope its a cure.

    But of the myraid of 912 floats horror stories, most have issues with starting and low rpm and with leaking fuel, along with cruise.

    The Lockwood Tech advised me to check the ignition wiring for possible grounding.

    Now the potential GOOD NEWS ....

    According to Lockwood's person who took my float order,                                                                                                                                                             the newest floats (starting approx 8-9 months ago) were developed by Rotax, they gave up on Bing. And they have cured the problem !!!                                        time will tell. She said they have an R on the floats.
