Get a hold of some one that works on these engines daily like a Rotax Engine Teacher. I have had the best success with a great guy named Bob Robertson. He gives you a honest un-biased opinion from the experience of real problems with real solutions. I have never met him but i have bought from him and had issues discussed on phone and solved. I call and he sends parts overnight and have the problem fixed once and for all. I have never heard or read anything negative about Mr Robertson. His contact information i have below for you.

This manual has a section which deals with mandatory and recommended maintenance schedules. This provides some guidance, in the form of an actual schedule, as to timing of such procedures as engine overhaul, airframe checks, and so forth. You may be able to adapt the schedule that they provide, to producing a maintenance manual for your aircraft. You can download the manual in html, PDF, and Word formats. You can find it on the AUF/RAAus website at www.auf.asn.au Look down the main page till you see the link to the Technical Manual. Hope this helps Colin Durey Sydney colin@ptclhk.com Regards Colin Durey Pacific Technology Corporation Ltd +61-418-677073 (M) +61-2-945466162 (F) ________________________________ Message 3 _____________________________________ Time: 03:32:11 AM PST US From: "Kerry Skyring" Subject: Kitfox-List: Michel in Sweden --> Kitfox-List message posted by: "Kerry Skyring" Hi Michel. As we're in the same time zone I can give you a quick reply. I am really looking forward to hearing about your trip and how you used the PocketFMS. Our S5 in Vienna is getting very close to being finished. We are looking forward to some nice long cross country flights. So good luck for the final leg and hope to hear about the trip. Kerry.

I do remember your first post. Since then, I rebuilt my carbs. The new needles were a failure. I experienced exactly what you are experiencing, but mostly on the left (Pilot) side. Like you, I tried everything. This mind you after 650 hours with no carburetor issues and the rebuild was per recommendation, rather than problem directed. Bing told me there were three needles. the Black one which is what you have - designed for the 912S. The Silver ones that I had and have now, and another one, bronze, I think and I am not aware of its purpose specifically. On inspection, there was nothing visibly wrong with the old needles - per the inspection guidelines in the repair manual - so the old one went back on the left carb and I was pretty much OK until I returned from the Idaho trip last week and had a little rough running as I taxied to the hangar and found fuel on the floor the next morining - about a tablespoon full. I guess I will find the time to put the old needle back in the right carb. As for what to look for, I haven't a clue, but the fact that my probalem started with the installation of new needles, suggests that the needles might just play a part in the problem. Maybe as some vendors claim, "there was a bad batch".

It came with an "induction plenum" with valves for primary air and carb heat air. It also has the advantage of tying both carbs together mechanically so they aren't as prone to shaking off. Based on info from the list, I decided not to arrange for carb heat. I took the valves out and used the two inlets to the plenum to put on two K&N RU-0800 fliters. I figure that this would allow the engine to breath easier. I used a few inches of scat tubing to connect the filters to the plenum. Seems to be working real well so far.
