So today was clean-up day. I had been getting that intermittent ACTV ADHRS VIB warning so I installed the new Vans rib in the back (what a pain - I highly recommend current builders do it while they can if it is not in the new kit), and I decided to check my floats to comply with the newly revised Rotax mandatory s/b....mainly because on my last flight I detected some fuel smell on decent, some erratic fuel PSI and FF readings, and a check showed some gas in left carb tray.
The carbs were balanced, and I don't notice any rough running - in fact during the last flight I was quite pleased with how smooth straight and level the airplane was running.
The syringe kits are not out yet so I calibrated and used my reloading scale, I could tell right away I was going to flunk as one float on the left carb (same side as the smells and overflow) was submerged and was noticeably heavy when I took it out of the fuel in the tray - even several hours after "drying out" (S/b calls for 2 minutes btw). Also the left cork float chamber gasket was apparently not installed correctly as there was a pinch in it when I removed it:
(the pair is supposed to weight 7 grams or less)
Here's the offending one (the "sinker"):
this one looks like it is going too....if a pair is supposed weigh 7 or less, I guess 1 should weigh 3.5 or less?
the "other side":
