A few months ago my engine was pretty rough when decelerating thru 4000 rpm to about 2800 rpm for landing.Like you,I synched everything so I just lived with it. I had an interest in a Kiev prop so I bought one. I removed my Warp and installed the Kiev for flight tests. I had it on and off for about 4 hours of flying. I readjusted the pitch each time to try and get the best performance. Alas, it did not work out . I could not get even my old cruise speed so I went back to my Warp.(sold the Kiev) One thing I did notice was that thru the mid range the engine was smooth as silk with the Kiev ! (as it was overall..what a nice prop )! I put the Warp back on and there was that rough mid range again (it has since abated) Perhaps the prop might contribute to the problem? I think the choke idea the guys brought up is certainly valid. I don't have a choke only a primer. My chokes are wired closed. My old nemis,diseling on shutdown (prop turns backwards about 3 revolutions) has cropped up again. I have fresh premium no alcohol fuel in my tanks too. I guess I will pour in some Octane booster and see if that stops it. I shouldn't have opened my mouth...the other shoe fell! Man, this is a full time job for me keeping this engine running good. I sure am glad I am retired and like engines! Good luck to you Scott and please keep us informed! Your problem will probably be mine tomorrow. Dick Maddux Kitfox 4-1200 Rotax 912UL Milton,Fl PS; I had the wrong Kiev prop on my plane it turns out.The wrong one was sent. Soooo I will probably give it another try. I sure loved it !!! ________________________________ Message 2 _____________________________________ Time: 10:45:14 AM PST US Subject: Re: RotaxEngines-List: Re: My 912 is still not happy-- From: Ollie Washburn I have 660 hrs. on my 912ULS and the only thing I have ever done is sync. the carbs, change plugs a couple of times and change oil @ 50 hrs. Gearbox was changed @ 250 hrs. for SB about bad metal in gears which mine had. Ollie On Wed, Mar 17, 2010 at 10:32 AM, wrote: > Scott, > Here are some other ideas you can ponder.
