It would make sense at 4 gal/hr and a 32:1 mix, but the model 2 (and 3) with a 582 is rated at a gas-guzzling 3.7 gph at max cruise of 85 and a more realistic 2.1 gph at 65; my experience being about 2.5 at 75. And the oil pump has to be set to deliver a ratio of between 50:1 to 70:1, or it would be out of spec. That puts your numbers below Paul at a factor of 3 to 4 times higher than actual consumption. I would not use that to determine the size of the plastic tank and I certainly wouldn't rely on a large tank to influence your C of G Pat - implying that you would go tail-heavy as you run low on oil! Just my humble and well-intentioned opinion...

At 4 gal/hr fuel usage a pint an hour would be 32:1 mix. About what one would estimate. I would size the oil reservoir so that you could go on a typical long trip where you would need to buy fuel to return without having to carry additional oil or buy it. So let's say for example you go on a trip someplace that is a half day away of about 6 hours and before returning you top off your fuel tanks. Total flight time of 12 hours would use around 45 to 48 gallons of fuel and that would require 1.5 gallons of oil. If that is not your typical long range usage model, then size it accordingly. Another way would be to start with the fuel capacity. Say it is 15 gallons. Then if you allow for 45 minutes reserve, at 4 gal per hour that is 3 gallons reserve and you have a net usable of 12 gallons or 3 hours. Topping off the fuel (without adding engine oil) and returning home would use another 12 gallons. Total fuel burn of 24 gallons and the oil tank would need to have capacity to mix 24 gallons plus 3 reserve gallons or 27 total fuel. Assuming a 32:1 mix then the oil tank would need to have a 6-3/4 pint capacity. So if you size the oil tank much smaller than a gallon, then you'll probably need to carry spare oil some of the time.

Here's some facts: The engine was purchased in 1989 so I assume that is a "gray head" It went for about 600 hours before a complete rebuild It is now a little over 200 hours since the rebuild I have the optional ground-adjustable GSC props and I think the "B" reduction gearbox My weight-and-balance shows an empty weight of 525 lbs With me and typical fuel = 732 lbs When I am solo I rarely go WOT, 6000 rpm has more than enough power, max rpm is posted as 6300 I typically cruise at 5000-5500, descend at 4000, idle at 3000 I *never* use flaperons for trim, I have a horiz stab tab that works great. I know one time I did a short-field takeoff and cruised for a while at 1 notch of flaps, I had a *lot* of trouble maintaining cruise and was no doubt burning a lot. Personally I think my model 2 is light, fairly clean (no added fairings no), and trim. Now if only I could say the same for myself! Personally I was a bit worried I was running a bit lean, especially with water temps high recently. But since the burn rate is exactly on spec and the temp gauge/sensor has actually failed I am not as worried. Spot anything there that might make the difference?

Two things recently that could affect it: 1. I had the dash off to replace the lord mounts, so 1st thing to check was open wires - nope. 2. On most recent flight the gauge went well into the red after taxi and was erratic. Thinking "better check coolant level" I did, when cold, and it was full to the top as well as a few inches in the overflow. The gauge has a good ground, a good 12+vdc, and 6.87vdc on the sensor lead on a cold engine and 60f day. I guess what I need to know is: should 6.87v pin the needle(hard!) on full scale? ie does anyone know what is the normal voltage range of the sensor, as in - does 6.87vdc = 60f? There are no manufacturer's markings on the gauge or sensor that I can find. Thanks in advance for any info or where to look.

I believe the "blue head" didn't come out until 1991-92 and mine was flying by then. Hard to believe that using flaperons for trim would increase drag that much, although I know as soon as I pull on the flap lever the nose tips down a *lot* (the difference between seeing the runway and flying blind) and I have to add power. I can also reset the trim tab for neutral stick - only with full flap does it not trim out but at that setting it's like having air brakes. How much flap do you need to add for trim? How does it fly with no "flaps" - nose up or nose down? Maybe it's basically tail-heavy and you need to add flap (ie drag) to fly level? As you add speed the nose tends to pitch up, so you add flap(drag) to counteract? Sorry so many questions but I have never used the flaps for trim so don't know. The PFA (oversight for UK KF builds) issues a build document that basically says using flaps for trim is bad, and describes the elevator trim installation instead. I don't have EGT gauges but should probably look into that, I feel left out. I changed the plugs and wires not too long ago and haven't checked since, should be about due. I had to change them for a different type because the plug wires had a tendency to get loose. I will inspect the plugs after fixing the water temp gauge and reserve warning sensor light problems are fixed. What's the ratio on these things - 15 minutes of repair per hour used? ;-) Almost as bad as a chainsaw!

There is a round steel oil reservoir tank with a plastic sight tube. The tank looks as if it has a 1 1/2 gallon capacity. My question is, isn't that an awlfull lot of oil. Are you 582 drivers carrying that big of an oil reservoir tank?

I used Pennzoil premium air cooled oil and mine looked the same after 400 hours. Generally the rings wear much faster than the bore.

The 582 grey head I purchased used was sold to me with 100 hrs as time on it. I pulled the exhaust off, looked in the ports and can't believe the cross hatch pattern in the bore. To me it looks as if the engine was never even broken in. The previous owner was in California anfd said he used AV2 oil. Over the last 30 years I have used AMS Oil in every type of 2 stroke engine application you can name. I swear by it. (Dave I know that the petro based oils give better corrosion resistance in humid conditions and I am a little afraid of the synthetic in for my plane as I know my hanger is not heated and condensationis a big problem. Now, after looking at my pristene bores after 100 hrs with AV2 I think I would be remiss not to use AV2. What do you guys think of AV2? do not archive Pat Reilly Mod 3 582 Rebuild Rockford, IL ________________________________ Message 16 ____________________________________ Time: 05:42:29 PM PST US Subject: Kitfox-List: Gearbox wear From: "corbob13" Guys (especially Dave), My plane's in for annual and my A&P is hesitating to sing the book because of an issue with the gearbox. When he drained the lube he noticed a lot of very fine metal particles in it. He's also worried about the amount of backlash in the gears. I thought the backlash was a little much but since I've only got a few hours on my engine from an overhaul I've ignored it. He compared the amount of backlash to other planes on the field with similar setups and found the others to have little to no backlash in the gear sets. I spoke to LEAF, who did the overhaul, and they said it was normal, both the metal and the backlash. I asked at what level the backlash should be a concern, but they said there was no limit. What kind of experiences have other had with their gearboxes? Do you see any amount of metal particles in the gear oil? How about backlash?

You may be chewing your gears. I'd pull it apart since it's almost trivial to do so. I notice, however, that the B has a spring actuated dog system between the drive gear and prop hub, so I can understand LEAFs telling you that metal particulate was normal. It may be that it's the dog that's worn and causing the backlash, and not the gear, or the spring has failed or is otherwise not providing sufficient pressure. How many hours total on the gearbox? I doubt LEAF did anything at all to the gearbox during the rebuild, so you're probably operating on the original time.

This is the way most of the Aussies have their CHT probes set up. I never have any signs of leak either. My CHT's read as we discussed earlier 275 - 295 Cruise and now as it is getting warmer here I am seeing up to 330 in climb. I recently modified my lower cowl again to get more air out.

I didn't like the idea of putting the probe under a head bolt as some have done, fearing the idea of putting 24 lbs of torque on a copper terminal, so I followed another poster's idea and drilled and tapped a hole in the head between, and slightly below, the spark plug locations. Now I find that the temperature readings are quite a bit above the reported 10 degrees or so difference (from the spark plug locations) that I have read about for the head bolt locations. I have looked into this and have decided that the spark plug probes (mine anyway) position the thermocouple wire attachment point...the point where the actual reading is made, the "business end" if you will, (and it is NOT the area that actually touches the head)...one-half inch above the head surface, and well into the airflow that goes past this area. This spark plug thermocouple is further insulated by having it *above* the spark plug gasket, making it even further from the cylinder head, albeit by a very small amount. I believe this 1/2" of separation from the head is enough to place the "business end" of the t'couple in the relatively cool air passing by. I used to see CHT's of an average of about 275=B0 F, while I now see my CHT's read about 350-360=B0 F, and up to about 385=B0 F in climb, at 1500' MSL, @ 80=B0 F ambient. Straight and level flight after a 5 minute settling down period after climbout will see the 350's I mentioned. My thermocouple attachment point...the business end...is now closer to the head, and tucked between the head and a fin instead of sticking up into the airflow, so I can accept the higher readings, especially when the engine is running so strong now and climbing better than I recall it doing before the engine breakdown. I might add that each flight sees lower CHT's as the engine breaks in. Any comments?
