    Hi Robert. Fix my 912UL carbs today. Cleaned and found some bildup in the mixer above the main jet (removed the main jet and could see it. Had missed it previously) This was only in one carby. Also replaced the needle jet and jet needle. The other was replaced when I bought the plane as the jet needle was bent. Also the rplaced the 'o' rings and used the Rotax float bracket level tool to get the float brackets exactly level. Pulls full rpm now. Should be flying next weekend.

    Cheers Mike.
