That's mostly what leads to the crazy parts prices, like the $60/meter water hose and $270 oil pressure senders for the 912, etc. You have that long dealer chain and foreign exchange rates, etc., that contribute to that. Not like the Lyc/Cont. engines have cheap parts either; they pay hundreds of bucks for little scraps of rubber too. But the Rotax is at least as bad and sometimes worse when it comes to parts prices. - The 912 is (or was) practically a disposable motor at overhaul time. The 2-strokes were still usually worth it to rebuild when they finally did wear out (unless you really had to replace everything inside it), but the 912's overhaul cost was always so bad that it was best to just throw it away and get a new one. I believe Rotax now has a short-block option for the 912 that (finally) makes zero-timing a runout motor a cost-effective option (Roger and Thom may know more about this?), putting it around 50 to 60% of new. Otherwise, some of the Rotax motors you can't do better. The 503 is still the best deal in aviation for 50hp to crank a prop on an airplane, nothing else comes even close in terms of purchase price, gearbox options, field experience on setup and use, etc. The 912ULS is probably about as good as you can do in the 100hp range at the current time. The new lightweight O-200 still weighs a ton and a half, costs about the same and I don't think it's even available yet for general purchase (?). The Jabiru is limited in terms of prop options because of the direct drive/high-ish speed operation. So it's not a good alternative in many light aircraft applications, such as lower speed planes like trikes, etc. And now with the 2000 hour TBO and (I've heard?) the short-block option, it's overall cost is a good deal for 100hp. So it's kind of a mixed bag. The 582, for example, isn't really cost effective anymore. Its purchase price with a gearbox is too high and there are competitors now that are a better deal (the Jab 2200 and HKS) unless you really need the power/weight. The 447 was one of the best motors Rotax ever made, but sheer market forces have apparently killed it at the current time. The 912UL is a little heavy for its power output and is only about $1500 cheaper than the 100hp. For me, it's not a slam-dunk for Rotax, it'd depend on the type of plane I was going to fly. But for LSA class planes it's probably still about the best choice overall plus or minus....

Every time I've stored an engine according to manufacturer's instructions, I had to clean the plugs thoroughly to get it started. AND that is all I had to do if it was running fine before storage. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Everyone is entitled to his own opinion, but not his own facts.

I thought there was something like that. Tom I pulled a plug and it was Carmel colored and dry. I will clean all the plugs and see if it works.

Having same issues as others with OP. I also put on order for $41 from kitfox a new VDO sender with - and + terminals. I was really happy to find the kit because I was not thrilled about shoppi ng around and figuring out what was needed. I called kitfox and ordered by phone, when asked what model kifox I owned I said the CH-701 model. they joked that the price was double for a 701. They were helpful and friendly. Here is a link to some pics of the kit from the teamkitfox forums. http://www.teamkitfox.com/Forums/showthread.php?p=11042 The parts look good quality and cannot say what the total individual parts would cost if you put this together yourself.
