Complied with service bulletin SB-914-055 "Replacement of circlip ( carburetor )". BDH gave me a hand and guided me through the procedure which was straight forward. Two heads are better than one and his expertise is greatly appreciated, thank you. The only thing that surprised us is that the left and right circlips were in a different positions on their jet needle. The left circlip was in position three and the right in position two. We discussed what we should do and decided that the service bulletin says to replace the circlip in existing position. The engine has been built by Rotax and test run by Rotax, so we decided to replace the circlips in the exsiting position.
