Before you take them apart, find specs on where to set each adjustable component when you are reassembling(for instance, how many turns in or out to set the idle screw. Someone helped me adjust my carbs and it hasn't run right since. The settings are out now, so using Pre-rebuild settings won't help. Where can I obtain this information?? anyone?? ----- Original Message ----- From: tom To: kitfox-list@matronics.com Sent: Thursday, August 05, 2004 10:43 AM Subject: Kitfox-List: Carb rebuilding rotax 912.

Any tips? --> Kitfox-List message posted by: "Kirk Martenson" Dave: I would call Bing at 800-309-2464 and ask them for help. I just ordered two rebuild kits for my 912 UL, as well as the Bing tuning and parts manual.

Do any of you who have a clutch in your re-drive have a separate tach for your prop? Any chance of ever exceeding the design rpm of the prop while in a power-off dive? Sounds like it might be more difficult to induce that problem in a Fox, but perhaps something some of the more slippery yank and bank types might have to be concerned about? Stu Bryant Atwater Ca.

I really would like to get some. I want to put it on critical components of the fuel and turbo system. Thanks Rick ________________________________ Message 6 _____________________________________ Time: 07:08:51 PM PST US From: "Rick" Subject: RE: Kitfox-List: RE: Kitfox-List Digest: 27 Msgs - 08/05/04 --> Kitfox-List message posted by: "Rick" Please correct me if I am off here, but if the prop goes supersonic I believe that is exceeding its design limit or at least its efficiency limit. I cant imagine a prop that would not be designed to operate right up to that point. There are some props that have a range of operation to be avoided depending on the engine prop combination. The prop builder knows which as this can cause fatigue and failure due to harmonics in a given range of speed. Some props work better at a given speed and pitch combination than others. Just a quick jab at a very complex and lengthy subject. The next prop I get will be perfect until I find the next perfect prop. And yes the NSI redrive uses a sprage type clutch. No prop tack but if you know your engine rpm and reduction drive ratio there is a formula to figure out prop tip speed, which is what I think you want to know and not prop rpm. I have it some where.

Ha ha. The stuff just happens to bubble up, or desolve away with auto fuel. Don't know for sure about Avgas. It formed a blister or bubble at two fuel seeps for me where the welds weren't solid. Easy to find the leak like that. I am not sure about it handling much heat like on engine parts though. But it should take any heat you would let get at fuel related parts. Be careful. It has Keytones in it so don't breath the stuff. Kurt S. S-5/NSI turbo --- Rick wrote: > Who was it that found some type of paint that would > show fuel leakage. I really would like to get > some.

As you know, the lower the prop pitch is in a dive, the faster it will spin. I don't know what the other props have, but the NSI CAP prop has a low pitch stop that should keep it from ever getting near the rpm limit. In fact, that prop turns a bit slow in normal use. I notice a major increase in thrust going up from say 5200 engine rpm to 5500. It isn't just engine output. Seems like better prop efficiency too. If you are pushing overspeed on your prop, you will also have a lot of drag to deal with. Enough you shouldn't miss it.
