I also like to keep things simple. Some years ago, the Brits made a marine diesel engine that was so simple that you could take the engine apart and rebuild it with standard plumber fittings. It was a one cylinder, big flywheel, heavy monster that you could start by hand. Exactly what you would want as an auxiliary engine if you were circumnavigating. But the idea never caught, or the market was too small, because they don't exist anymore. Anyway, I like the idea too. I guess, if you control mixture, you need EGT, right? I will consider it, but not this year. First, I need to fly and know my new Jabiru. Then ... with time ... when I get money that I don't know how to use ... :-) Keep us informed on the performance of your carburettor, Bruce. Thanks in advance.

I just need more heat in low power setting at economy cruise especially when it is cold out. Rick No, I don't have any pics of the sliding type.

I had read about sliding-throttle carbs way back in about 1970, and decided to build an injection system for a Chrysler Hemi. It was quite simple to build, because the intake ports were equi-distant apart, which would allow for the sliding throttle plate to have 4 equally-spaced holes in a 1/8-inch plate, controlling air-flow through a 1-inch aluminum body. Without going into all the details, I built this thing at home, using only my lathe and milling attachment, and various cutters, etc. When it was finished, I was going to warm up the engine (it was winter here in Michigan) with the carb and manifold installed, then quickly remove the carb and manifold, install the injection unit while the engine was still warm, and try out the new unit. The engine would not fire, soon running the battery down. After charging the battery overnight, I gave up on trying to start with the carb, and removed the carb and manifold, installed the injection unit and the engine fired in about four seconds cranking...and what response! It was a little sticky, due to the vacuum acting on the sliding plate, but it worked fine. It looked a little strange with the 8 injection tubes sticking up about a foot, and all moving back-and-forth as the throttle was blipped. As far as trying to build one for an airplane engine, I've gotten a little more chicken-s___ in my later years, and probably would not try that act again.

To which Michel sez: >Did you had an oxygen bottle, Mike, or did you just keep your breath? :-) We have an O2 bottle in the Turbo Arrow that I borrowed for the high-altitude testing in the 'fox. I really don't know how high either of them will go because, although I've had the Arrow to FL200, she was still climbing 700 feet per minute through FL190. Turned in a rather impressive airspeed of 175 KTAS (200 mph) up there--I was very proud of her! :-) Mike G.

I have a 618 radiator with a 582 and the strip technique is just too inflexible. Ideally I'd like to install one that has the flap in the back but I'm not wedded to that idea. So, if any of you can help me out I'd be most grateful.

My Problem was mainly radiator baffling and even more coolant air exhaust at the rear of the cowl. In studying other airplanes on the ramp I noticed that a Maule had an adjustable flap at the rear bottom of the cowl to increase or decrease the airflow through the cowl. I enlarged mine, but now wish I had hinged it with a control rod like the flaps.

The AeroCarb could fit the bill. Would eliminate the sync hassle and may even make the 912 run a little smoother throughout all RPMs. What do others think?

Manual mixture control I liked. Also let the Jab produce more power at full throttle. It seemed much smpler than the Bing. However, I have had a history of sticky and then stuck carb slides due to my carb being an early version. I now have updated parts, which includes every part except for the bell which attaches to the engine. Just did the first test run and flight on the new parts today, and it worked quite well. Even with the prior problems, I had accumulated close to 100 hours over 1.5 years.

They are the local Rotax Distributor. It is heavier and more difficult to install than the flappers that Lowell Fitt makes and uses. I was unable to install them on my plane because of mounting restrictions. It work well and is much better than flying without, as I was is the past.

My cowling leaks. --> Kitfox-List message posted by: James Shumaker I used some P shaped weather stripping that is available at the hardware stores. It measures about a 1/2 inch along the spine of the P and about a 1/4 inch on the peak of the P. First I filled the inside of the cowling for about 2 inches from along the perimeter where it meets the windshield. Then I stuck the sticky side of the P to the cowling. The sticky side is >P the left side of the P. The P is now compressed against the windshield and is not even visible. There is a little bit of runoff into the cabin but not much.

I have just repitched the prop to obtain around 6200 static. When I recently did a rebuild on the 582, I found that the previous owner had removed the thermostat altogether. Engine does reach it's desired temperature (50C I think) before full power is applied. Normally reaches that temp by the end of taxi. In flight the water temps are stable at about 10 below the maximum - it rarely moves. My radiator hangs out in the breeze just in front of the undercarriage, with no cowls or fairings. Hope that helps some.

I need to know what size thermostat some of you 582 drivers are using. I have been told the 135* should be used and not the 165*. Any of you using the small radiator without any flaps,doors,covers or what have you and the engine runs fine? I have a Model II that just got the air worthy certificate and afraid to fly it because of the d-- engine. Some say 135* some say 165*. Static turns at full throttle is 6850. Exhaust gas 1150. Static rpm I was told by a power parachute driver should be around 6200/6300. Some of you experts 582 drivers jump in here and tell me what I need to do. I'm like the guy with the Model 7 and no engine. Feel like selling it. All help appreciated.

We plan to leave around the second weekend of June from the west coast and go north via the Trench in British Columbia to Watson Lake, up to Dawson City, then a jaunt along the Yukon River to Bettles, then back on the river again to possibly Nome (weather permitting) and then down to Anchorage. The trip home would depend on a number of factors, to be decided later. We would stop at a couple of hot springs on the way and make a stop in Bettles just to say we were above the Arctic Circle. The trip would take three to four weeks, depending on where folks were coming from and the weather, of course. We will be camping many nights and staying in lodges and motels other nights. We may even find a friendly hangar to stay in. A few considerations for you to think about before you decide to go: 1) are you proficient in short field landings and otherwise very experienced in your aircraft, 2) are you comfortable with tricky weather conditions, 3) will you be able to get away for 3-4 weeks, 4) are you comfortable flying over adverse terrain (many times without roads below), and 5) are you and your aircraft up to flying a hundred or so hours in 3-4 weeks. Robert has flown his Kitfox to Alaska twice, once in 2001 and then again in 2002 on John King's trip. I lived and flew in Alaska for six years in the 70's, at which time I flew a C-172 from Seattle up the Trench to Anchorage, and then I was part of John's trip in 2002 in my Kitfox. Let me know if you are interested and we will keep you informed and answer any of your questions. Stan Specht N16KC "Columbine" Kitfox Model IV Speedster 912ul
