For over a year my 914 had an issue which resulted in a low power output. Additionally I have been frustrated and by a hard starting condition from the time I installed the engine into my plane. Unable to find anyone who worked on 914s in my area I was ready to remove the wings and load the plane onto a trailer and haul it up to Rotax Support in British Columbia for a solution.
I had worked with several Rotax Heavy Hitters looking for a solution. Roger Lee a contributor on this forum suggested I call Rick Wright of Copper State Aero (www.Copperstateaero.com). Rick is located at Ryan Field, on the south side of Tucson, as is Roger. Rick supports the 9 series Rotax engine especially the 914 and the up side is that Rick makes “house calls” traveling around the US pulling a 38’ trailer set up as a work shop. This is a good thing since I didn’t want to fly with the anemic output of my engine.
Rick visited my airport, and evaluated the problem based on his experience as the US representative of Stemme sail planes and solved the problem.
The bottom line is, with Rick’s involvement my engine is purring better then when it came out of the box.
Thanks

    I'm really happy for you Bernie, and it's great to hear about those who can and do give good support, but what was the problem and what was the solution?

    Thanks for the comments. In November 2011 I had what was diagnosed as a failure of the airbox sensor. To get to that point the shop that I took the plane to had several young techecians disassemble the carberators apart to rule out that as the problem. In the course of the disassembly I believe some errors were made and componsnts inside the carberators were scored preventing fuel flow from smoothly working. I had another independent technician work on the engine but his experience on 914's was limited. Since I moved to Arizona I had a "Heavy Hitter" technician rebuild the carberators. Engine operation was inconsistant, meaning some times the engine would develop full power with all readings correct then the engine would revert to limited power output, something I would not fly with.
    Rick Wright, Copper State Aero visited and after looking at the history, inspecting the carberators, recommended that the carberators be returned to Rotex Support Centre in British Columbia for evaluation. After all the work performed on the carberators, I wasn't in full agreement with that but Rick had quite a bit more experience so off they went to Canada. Service Support determined that the throttle position sensor was not functioning and the internal walls were scored. Their recommendation was not to perform further work plus after all the frustration I had experienced I decided to order two Bullyhawk carberators. The new carberators corrected the engine performance. Since the beginning after I installed the engine it had experienced difficult starts which I attributed to the ambient temperatures. Somewhat close to the truth but Rick found a break in one of the CDI leads inside shrink tube of a factory connector. The connectior was repaired and the engine starts within one turn of the prop.
    Not much else to say. If I left anything out please let me know.
