Take a MM ruler and stand it upright (straight up) on the outside lip of the carb. Now slide it over towards the float armature so you can see the ruler marks next to the float armature. The top of the float armature should be 10.5mm. If it is not just bend the tab where the float needle is suspended to obtain the proper 10.5mm height. This is what controls the fuel level in the bowl as the floats push up against it. If it is off adjustment it can cause some flooding and rough running. -------- Roger Lee Tucson, Az.

True story. When I was building my first airplane in the late 90s, a friend started his as well. We were pretty much on a parallel course. Like you, he was concerned about the abundance of service letters and bulletins from Rotax, so he opted for a Subaru EA-81 which was then supported by our kit plane factory. The Subaru conversion company was completely, read COMPLETELY, silent on anything at all and that gave him great comfort. I stayed with my gut feelings and went 912. I first flew in 1998 and subsequently put 900 hours on mine. To this date, he has less than 40 on his and it has been up for sale for at least ten years with no takers. I also have a very good friend who flies behind a Jabaru. I have helped him with some issues. The inside of his lower cowl looks like a catch basin for an oil change bay. He has had one overhaul in less than 400 hours and now no longer has to re-torque the head bolts after every flight, but still adds oil after every flight. Neither of these guys have ever been on any type of email list or forum. If you really feel that no news is good news, then good luck to you.
