Bigelow" Subject: Kolb-List: High Altitude Compensating Carbs --> Kolb-List message posted by: "David L. Bigelow" Interesting reading about John Jung's experiences at high density altitudes. I installed HAC carbs on my 503 powered FS2, and have not been sorry for the expense once. Here on the Big Island of Hawaii, it is not unusual to range from sea level to 10,000 feet during a single flight. This past Sunday I took off from my pasture strip, (density altitude of 5,500 feet) flew across the saddle between Mauna Loa and Mauna Kea at 8,000 feet, flew down the east coast at 500 feet, shot some landings at a near sea level strip, and then back home. Although there is quite a performance difference between sea level and the higher altitudes, the EGT varies very little (at the same RPM) with altitude. This tells me the automatic mixture compensation is working as advertised. My little ship seems happy cruising at about 50 mph IAS, which takes about 4,900 rpm near sea level, and 5,100 rpm at 5,000 feet. A two hour flight with some climbs and descents burns 6 - 7 gallons.

It was held in the second week in July, and it was very hot. I got there early, and as the morning passed large cumulus clouds began forming and you could see little localized thunder bumpers passing by to the south. As the morning wore on the clouds grew in size and the localized showers to the south began moving north toward the airport. Just before the airshow as to start, I called the tower on my cell phone to get permission to leave. I taxied out and took off. I was heavy and like you I was surprised how long it took to get the FireFly off the ground. My initial mistake was not worrying about air density. My second mistake was trying to be too helpful and clearing the runway too soon. I lost the runway thermal and I was out over the grass. If I had not had a vertical climb indicator, I would have put it back on the ground. But I could just make a positive climb of about 50 fpm. Also, I could not run the engine wide open because coolant temperature would exceed the upper limit. There I was out over the Mississippi River bottoms south of Cape Girardeau in massive sink and I had to pass over Cape Girardeau to get back to Perryville. I turned and flew over I55 that passes north and south through Cape and picked up the traffic and pavement heat. This pushed the climb rate up to 100 fpm. On the north side of Cape, the FireFly finally reached 600 feet and away from the moist air over the river bottoms and the climb rate went up to 550 fpm. The rest of the trip was uneventful except for a few sprinkles. One other experience with massive sink. In the early days of my FireFly my wife's cousin wanted to see it. I flew FireFly down to East Prairie, Missouri on a hot mid July day. East Prairie is a little town located in the boot heel of Missouri and on the Mississippi River bottom. At this time the FireFly was powered by the 447. On the way I flew at 2,000 agl and as I passed over the edge of the town the bottom fell out. With the throttle wide open I was still losing 200 fpm. I had flown over a little green town in the middle of the surrounding farm land. I turned and flew back out into the country and everything returned to normal. After the airspeed indicator, I believe the vertical airspeed indicator is the next most important instrument. Enough of the ramblings of someone whose FireFly is 300 miles away. The wife's last official day was yesterday, and so she will be here today. Hopefully we can go retrieve the FireFly next week. Jack B.

They greatly aided my decision to buy one last year. I also have a Cessna 180 Skywagon, 230 hp, taildragger. Its gross weight is 2,550 pounds. It's got the 6:00-6 tires on it. I calculated the ground contact pressures and found that at my gross weight, these tires give about the same contact stress on the ground as the biggest 8:50-6 tires on the heavier Cessna 185, which if memory is right, grosses at 3,600 pounds. I've landed on sandy mesas, grass fields, and even a beach once, down in Baja, with the waves crashing and a brisk crosswind. The only time I've felt that my tires were too small, it was my tailwheel tire, a stock 8" tire. I really should change that to a 10" tire sometime. Don't ask for my opinion of the inky-dinky tiny tailwheel tire that came with the Firestar! As the tire sizes get bigger, each main-gear tire size change slows the Skywagon down 2 mph per size. They also make landings and take-offs slightly more difficult, due to the increased sideward flexibility. I can really feel the additional rolling inertia as larger tires spin up, landing. On the Kolb, larger tires shouldn't really be necessary. But I doubt they'll hurt. They will improve the static angle of incidence in the 3-point attitude. For price, one thing to check is whether you can find used tires somewhere. They'll be lighter and that's a benefit. Can't imagine you'll put any wear on them. There's another potential benefit: smooth tires, slicks, are easier to land with on pavement, because they slide sideways easier. I've been running slicks on the Skywagon for about 15 years now, and wouldn't have anything else. I'd like to put the 6:00-6 tires on my Firestar II. Do they fit the wheels? Hate to admit it, but I don't know what size wheels they are, except that they're stock. Dave Paule Boulder, CO FS II Cessna 180 Skywagon > After seeing the Kolbs that flew into MV, I get ideas of how I'd like to change my Firestar. One is tires. I have 6.00 X 6.00s and they do the job fine but the 8.00 X 6.00s look better. So I checked into them and they seem to cost about $100 each for the tires plus more for the tubes. That's more than double what the 6 X 6's cost. Is that just it, or am I just not finding the best source?

Yea, the Big Muddy is a HUGE sink-- I was flying a hot air balloon over it several years ago and was at equilibrium at 2000 feet. Wham, went over the river and had to go to both burners to pull out of the sink (25MM BTU's of power). Ended up pulling out at around 150 feet. All of the other balloons experienced the same sink.

Richard Swiderski -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Edward Steuber Subject: Kolb-List: Stuck rings --> Kolb-List message posted by: "Edward Steuber" I had a problem starting my Cuyuna UL202 and found it had low compression on both cylinders . It only had 30 hours since the cylinders had been rehoned because they were too tight with the pistons. The clearance before was .003(too tight) and after .007(correct) but the paperwork from the shop does not say anything about cleaning or inspecting the ring lands. I was told that many of the original Cuyuna's were sent from the factory with incorrect tight piston clearance that caused many failures . This engine had already been repaired once because it has the .010 pistons . Upon dissassembly I found both rings on one piston were stuck and one on the other. I believe they were overlooked and reassembled. But there is one question I need answering.... The pistons are .010 Wiseco's that are different from the standard Cuyuna pistons in that they have much thinner rings.........could these sticking rings have been caused in such a short time by this ring-piston combination ! ? The thinner rings have to run hotter...I have been using the same 2cycle Pennzoil air-cooled oil and Mobil premium fuel with similar temps as the last Cuyuna UL 202 that I operated on another Ultrastar I flew for 100 hours with no trouble. I use a 40 to 1 oil mix as the book says and my egt temps were about 1150 with the lower compression cylinder (pto) running about 30 degrees hotter...I was told by a parts supplier that the Wiseco piston is an after-market alternative and not as good as the originals because they run hotter. Any of you experienced Cuyuna drivers have any info on this problem ? Since cleaning the carbon out and reassembly this engine has really good compression now ...I am looking forward to flying it with the new found power...it has to make a difference. What can I expect from these pistons in the future ? I know there may be some on the list that might have poor opinions of the Cuyuna's.... but all comments will be appreciated... carboned-up ED in Western NY ________________________________ Message 18 ____________________________________ Time: 05:58:24 PM PST US From: "nmatthew" Subject: Kolb-List: Firefly --> Kolb-List message posted by: "nmatthew" I have a Firefly; the top tube of the fuselage is stamped UL 029, and I checked the fuel consumption this weekend, its almost 5 GPH.
