    Subject: Intermittent 912 ULS problem
    Thanks to everyone who has responded and sorry I am a bit slow getting back. We changed the fuel pump to the new recommended model on the weekend and experienced the problem again shortly afterwards. Hoses are all brand new and mill spec. In fact everything firewall forward is new and by the Kitfox S5 installation book. We also have a facet pump and filter. Have not yet tried taking that out of the equation. What i did not mention initially was that when the problem occurs, pulling on some choke leads to a slight increase in rpm. About 100 I think. Would this be normal?

    Subject: Intermittent 912 ULS problem
    Kerry, the reason I asked about the milspec hose is that they have had a long history of causing problems. Although there are no visible external clues, auto fuel additives tend to cause them to quickly deteriorate and swell shut on the inside thereby inhibiting fuel flow. I don't know how long you have been using them, nor if this is the cause of your problem, but it sounds familiar and worth considering. If you use auto fuel, I'd suggest replacing them anyway with non-milspec fuel line. Pulling slightly on the enrichener cables (choke) and getting increased rpm is IMO confirmation that you are having fuel starvation problems. Careful analysis and elimination of potentials will soon take care of your problem. My recommendation is to make one change at a time, test fly, then make the next one. Otherwise you won't be sure what the actual problem was. Good luck.

    Subject: Best prop was: Fuel consumption based on gallons
    per hour Lowell, It was your recounting of their experience that finally pushed me over the edge to shorten the Powerfin prop. I don't have good climb data. I just can't seem to get stabilized long enough to get the data. It took me a while to dig out the pitch data. I align the blades with a home made laser tool because I feel it is more precise, and don't usually measure the actual angle. The Powerfin data is from their feeler gauge data. The Warp Drive is measured at the tip of the prop with the Warp Drive protractor. I tried to add the pitch to the table in old post below but will also summarize. 72" PF climb pitch 11.3 degrees, Cruise 12.5 deg 70" PF climb 12.5, cruise 13.2 70 Warp climb 12.6, cruise 14.75 I plan to go to about 13 degrees on the Warp Drive prop as a compromise, but close to the best climb area. I think that this will be a pitch that does not allow the engine to over rev in level but come up close to redline.

It correlates exactly with the PowerFin performance my friends had on their Model IVs. Although I flew along side them for numerous hours our performence data was anecdotal at best. They also did the 1 inch cut at the ends and it helped a bit as you report. Do you have climb figures and I am sure the actual prop pitch would be of interest if you have that.

    Subject: Intermittent 912 ULS problem
    Kerry, Yes they were new. They were dirtied up by some junk (polystyrene?) left in the tanks and dissolved out by the first bit of gas in the tanks. Then as the gas evaporated in the carbs, it left the junk behind. I had washed the tanks carefully with water and soap, but should have done one wash with acetone. If you can move the "choke" easily by hand, that is not your problem. Make sure they work smoothly by cable. Mine did initially, but after about an hour run time, it took a lot of force to get them to move at all. With some help from the list, I took them apart, cleaned some ugly yellow "varnish" off of them with MEK, dumped my tanks, replaced the fuel filters and no more problems.

    I felt I should add to this post that what I wrote below is not absolute because what I'm passing on is information that has been exchanged many times on this list over the years about Milspec hose. I don't know if there has been any scientific data to support what I've posted below, but I have heard enough reports of it that I tend to believe there is some merit to not using the Milspec if one plans to use auto gas extensively.

    Subject: Intermittent 912 ULS problem
    I might be way off base here. The problem may not be a fuel problem but one of too much air getting to the intake side of the engine. Have a look at the carburettor boots. Tug up and down on them to make sure they aren't either loose or cracked. Do you have EGT gauges? Does the EGT rise when you are having the problem? It could also rise and then sharply fall. How do the plugs look? Check them as soon after a flight as possible with as little operation post problem as possible. If the plugs show a white powdery contamination then the engine has been operating too lean.

    Subject: Intermittent 912 ULS problem
    I am going to give my 2 cents worth here. Everyone else has. First, I think that my engine has more time on it then most other Fox'es. Over 800 on this engine 912ULS. When I first installed my 912ULS, it started up very nicely, ran for a few minutes, loaded up and quit. Removed the fuel bowls and drained . Restarted the engine, same problem. Called Lockwood and they thought it might be over pressure on the float valves. Before I ordered a new one, borrowed my old fuel pump from 912UL. Same problem, Called one other person that had a 912ULS, he said he had this problem and after an hour or so said the problem went away. Great. Thought about it for a while and concluded, maybe vibration problem, I did have side springs on carb. Removed them and the problem went away. Spent a lot of time running up engine etc at airport testing, checking etc. Flew to Tracy, California. I went to start the engine and it kicked the carbs off. Couldn't seem to keep them on. Brought trailer to airport and transported it home, 75 miles. I put the carb springs back on, cleaned the boots very well and tested. It ran perfect, that is when I developed the starting technique that I put on the list. My engine has run perfect for over 800 hours. My advise would be, keep the electric pump turned off. To have a system that would help if mechanical pump failed is too complex to be effecent. If the Rotax pump failed, and you turned on your electric pump you would fill your crankcase with fuel, if you had it plumbed with seperate fuel feed, would be very very complex. I would suspect a piece of dirt or something like that in the carb. The engine is designed to act as 2 seperate engines, each run by seperate carb. Remove the carbs and check jets very carefully. Mil 6000 fuel line, I don't think is a problem and If anyone has some new they don't know what to do with, will take it. Good luck.

    Subject: KITFOX trailer for sale
    From: "Brett Walmsley" <n93hj@comcast.net>
    I am cosidering buying an enclosed trailer for my model IV. I have an original Skystar OEM trailer for sale. Thinking maybe $1200. It is the trailer that hauls the fuselage level. I have pictures if anyone is interested. It will also fit the Grove gear WITHOUT wheel pants. It is located in Savannah, GA. -------- Brett Model IV 1200/912UL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=103285#103285

    Subject: LANDING GEAR
    I'm trying to rid myself of some extra parts. I have a pair of "like new" landing gear without wheels or axles. They're already primed and painted. They even have fairings. The gear are for a taildragger, I just don't need them. If anyone could use a great pair of "legs" for your kitfox I'll give them away for $250. Call me at 262.483.7757 or email me at kopecky@milwpc.com. I hope I'm not breaking any rules by "advertising". I'm just trying to share parts that I really don't need.

    Subject: LANDING GEAR
    Sorry I don't need the "legs" what I do need are the hubs and wheels or even just another set of wheels. They could be either 6" or 8" rims as long as they bolt to the Kitfox 6 bolt hubs. Anyone know of a source?
