Phillip, Bummer to hear that you had problems with the Rotec TBI. I have around 280 hours on mine. There are lean issues with this carb. Whenever I climb above 9000 feet, it would start to lean out. I have to pull the throttle back a smidge to get the temps back down which cuts down the power available. Once leveled off, all is well. It is annoying. I sent it back to them early on to help. Well...... I plan to open it up at next inspection to open up the holes at the full throttle end. It should help with the leaning tendency at full throttle. You do have to learn its ways compared to a regular carburetor. Then I put a Duc carbon propeller on the KR looking for better takeoff performance relative to the cruise performance. Its nice and smooth, looks good, but now I fly a slower airplane. It replaced a Ed Sterba wood propeller (64x72). Go figure. I am still tweaking the pitch. Happy flying Roger Baalman Oklahoma

That carb is supposedly an Ellison copy but apparently it's not a very good one. It's quite pricey and shipping from Australia to the U.S. is enormous for some reason. Maybe Steve G. has put the Ellisons back in production? Mike Stirewalt KSEE
