SB 14-10-14 and Rotax SB-912-067 UL R1: Disconnected the carburetors from the engine and removed the float bowls. Installed replacement floats (2 each side) and gaskets which I got from California Power Systems. The original floats have the same letter "B", similar to the replacements but my engine serial number is affected by the service bulletin. Reinstalled the carburetors. I was able to replace the floats without removing the drip pans which is more laborious. Installed the air filters on the carbs and safety wired them.
Removed the F359 wire from pin #18 of the old autopilot backshell (WH-00026) and inserted it into pin #18 of the AP backshell of the SV-AP-KNOB harness. This was what was done by other builders who had the SV conversion harness (like myself) who added the SV-AP KNOB Panels. Hope it works.
