I have looked everywhere for 17mm ID heater hoses and have not found them here in the US. Even the hose companies mentioned by some of the members, don't list them. I too will reluctantly pay the $120 for two meters of this hose from the Rotax dealer. I had thought about covering the hoses with fire sleeve where it comes in close proximity to the muffler. What type of clamps are you using? The Corbin (wire style) or the standard automotive gear style? Lockwood recommends the Corbin but the parts book shows both and the prior owner of my engine used the gear type.

I purchased from a guy I think in Sweden, Europa has some custom needed hoses. I am trying to use as many spring type clamps as possable. Search Silicone hoses: http://forums.matronics.com/viewforum.php?f=9 McMaster has some spring clips: www.mcmaster.com also have a look at these places for hose and clips and other cooling stuff: http://www.sporthoses.com/parts/ http://www.dockingengineering.com/ http://www.summitracing.com/?Ntt=silicone+hose&N=700+115&Nao=100&Ntk=KeywordSearch http://rotorclip.com/ http://www.highwingllc.com/radiatorshutters.html Ron Parigoris BTW I purchased clip tool from McMaster, worth it, a lot cheapier and hurts a lot less than loosing an eye.A lot of energy in those clips once compressed. ________________________________ Message 3 _____________________________________ Time: 08:44:49 AM PST US Subject: RotaxEngines-List: Re: 912 hoses and clamps From: "lucien" [quote="Dick Maddux"]LS, I am pretty much of the same mindset as you are.

Thanks, Dick Maddux Kitfox 4 912UL Milton,Fl > [b] Hi Dick, Well, I'm probably going to let Rotax put it to me on this too and just get a set of the Rotax spring clamps. I have the original clamps on there since the hoses are from when the engine was new, but it occurs to me it's probably not a good idea to reuse them. I'm told the spring clamps are the only type you want to use here, so I'm erring on the side of conservatism on that. Going to be a bit expensive in the end, but hey, it always is.....

Copyright 2008 rotax-owner.com p.s. I have installed two of these and the customers are tickled pink. They got to start their engine's at almost 85F on a 18F morning. They put them on a timer and the plane was ready to go when they got to the hanger. Pretty easy to install, too. If anyone here is interested I may be able to help a little on the price. -------- Roger Lee Tucson, Az.

I finally had a chance to run it yesterday after gapping the plugs to 0.018". It seemed to run a tad smother but did not help it gain any RPM. Last night I decided to swap carbs from left to right and try the "three finger test" again. While I had the carbs off I decided to pull all the jets and again verify the sizes. The sizes were all proper. I used a magnifying glass to look carefully at each one. I could see light through each jet when I held it up. before reassembling the carbs I took the main jet and needle jet and gently inserted the needles into each jet just to see how far they would go up the taper of the needle. One of the Main jets did not go as far as the other. I gently twisted and heard (more like felt) a subtle snap. The jet then slid up the needle as far as the other main jet would go. The best way to describe it is there was a crust build up in side the jet. Prior to this I did spray the jets out with carb cleaner but now I know that was not enough. Took it out today and tied it down and got it to run up to 6200 RPM. Thank you again for all the helpful suggestions. Ray W.
