John,
Any chance that ethanolalcohol in the fuel is changing the composition of the o-ring allowing it to slip out of place?
I've seen some Mil-6000 rubber hose literally swell and dissolve when expose to autofuel over extended periods of time.

There are different types of rubber used in o-ring construction, nitrate and butyl being a few. Each is only compatible with certain fluids. Some will fail at low temps in the wrong applicaton
Here is a good reference for o-ring material....

Just brainstorming here.... might mean nothing.

I should have taken photos but heck it was to cold for shutter to work lol .
I cleaned out strainers and had great fuel flow I thought . Fired engine < actually started engine Runs great at idle thru 5600 RPM then wham she runs out of fuel after that . Without EGT's would not be able to see temp spiking. ERGO fly with EGT's .
Rebuilt fuel pump and checked fuel flow, again Great flow no probs . Started engine , didn't fire it yet . Idles smooth and runs to 5600 then wham EGT's spike and runs out of fuel . .

Now i get pissed and rip out all plumbing and start checking from tank's out WHOOOOOOO 3 way fuel selector has a oring that is crossways in throat of line when normal flow is going it lets fuel by , but when a suction is applied then the oring closes off the opening , not good for flight or EGT's or the engine for that matter . This is the second valve that has done this to me . These are the 1/4 " valves from Leading edge and also ACS that are silver and for fuel . I will not use these ever again and recommend others not use them also . I am re-plumbing tomorrow and using a real 3 way fuel valve that cost lots of money but is much cheaper in the long run than rebuilding the engine or the plane and makes me feel lots better to have that fan turning up front .

Again my signature will follow below

Damn Steve why the heck you using EGT's . People are saying you do not need them over on the other site lol . I personally would not fly without one unless it broke in flight . ILL DO A NEW POST AND SAY WHY .

I GUESS ILL LEAVE A SIGNATURE IN HERE

Leni,
I don't think that will be an issue. 100LL dosn't have all the yucky additives that I believe were causing build-up problems. It's the excess lead in the 100LL that (research indicates) is not necessary in the 912 UL. But that can be handled with specific oils and more frequent filter and oil changes. I read all over of flight school using nothing but 100LL for 1000+ hrs, but the proper service intervals are maintained.

I might just have to stock up on Rammon Noodles so I can afford Avgas. (Damn...I hate it when that happens.)

bet that is due more to the valves than the 100LL.. The question now is how long will it take for your valves to get shitty again with the 100LL.

Another "test" flight.

Ya all,
Just got back from from a nice flight, everything purring right along.
The EGT was still about 20' higher then I have seen in the past but it never exceeds 1500F at any rpm, up to WOT.
She's doing 90 mph @4800 rpm with plenty to spare. The engine seems to "sound" stronger using the 100LL, but that might be due to the cleaner intake valves and seats.
I hate the price of 100LL, but if the next few hours are as good as today I will stick with it, or possibly work up to a 50% mix with autogas.
Didn't have to take the cowl off before..., or after the flight. That's a good sign right??

I wonder if he was eating lead paint chips as a kid?

I sooooooo wanted to post over there but figured what I was gonna say would get me banned permanently..

So, whos plane is in his signature? his or Noels? Or is it one hell of a coincidence that they both have the same floats, cowl, and single float landing/takeoff technique at the same lake, same course same altitude?

I just dont think some people "get" it. The ENTIRE purpose of a forum is to exchange information. If they say that you can start a thread, but only reply to it in PM's or offline emails then what f$%^kn good is the forum. Hell I can save myself the trouble and just email 3 of my buddies and tell them I just got back from a killer flight... I find that most people want to share good experiences. I really do enjoy reading about others flights and the exhilaration they get from flying. But when I post up a story, get 50 people to look at it, and not one online reply it makes you feel like your story, idea etc. is not worth a shit (and some of them aren't ).

Sooo for those of you who like to dress up with high water pants and use a pocket protector why dont you try a little lighten up and let others enjoy this hobby life blood we spend most waking moment thinking about.

Hey no more friggin idle chatter and stick to the damn subject and be totaly serious for once . I can stand this any more all this crap and no good ideas from a couple of crazy guys lmfao.
OK it wasnt the seal oil , its that darn leftover wooly mammoth crap the oil company's are making into gas these days and it is varishing and gumming up real bad just like the pic you posted Steve. .

As for how many Alaskan's it takes , Enought till we get r dun lol . Heck steve without your input we would be lost without a real tech to give us good sound advice on how to check the muffler bearings or such .

Fly safe and check the finger strainers everyone

back to the topic..Last time I flew it was when I putthe new 72" prop on his plane.. I went from a 68" high pitch blade IFA to 72" low pitch. I had checked the jetting as the temps had dropped but was still getting higher than normal EGT's. I just pulled the power back, dialed in more pitch to get the EGTs down and flew around...Now it hits home.. I attributed the higher EGTs to having less pitch and the engine not workin hard....in reality, I was running out of fuel and trying to burn it down...hmmm. maybe we should learn to listen to the plane when it is trying to tell us something..

Well I would say he is directing that at several guys...Dave refuses to put the sig up to... you know what really kills me is his line of thinking. First he says something along the lines of ..We want you to put your name and location etc. as a signature to help make the list a more friendly, personable place... then you get for trying to talk and be friendly... MAKE UP YOUR DAMN MIND...

They were pissin and moaning too much about our use of whale oil so we switched to seal oil. Now we may have to try walrus or something

Hey John...
Have ya heard this one...?

How many Alaskans does it take to........

BTW...
The finger strainers are plugged in the tanks

Quit using whale oil in your mix. Just my tech suggestion.

I just saw that too. WTF?
Who do you suppose he is refering to as not "including" a signature?
Could it be that trouble maker 84KF.?

I hate that dude. All he does is give tech advise and provide FAA references.
Totally un-called for.

Of course, something like this isn't CONSIDERED "chatty".....

Jim,
How do you drive them? I mean, what electrical signal do you
supply and how do you control it?

Thanks,

high EGT 582 GRRRRRRR

Leni and I started to experience higher EGT's in my Kitfox we thought it was due to the weather change . I went out yesterday to rejet and now the darn thing does not get enough gas lol . Hmmmm bigger jet no gas . I did a fuel flow test and at static had plenty but with vacumm oooooops no fuel hardly . The finger strainers are plugged in the tanks . This happened once before when I bought the plane and had to steam the tanks out . Thought we got all that crud out but now I realize NOPE got to do it again. This really sucks when it is freezing out. To do the front tank stainer I have to pull the engine and remove the housing inside the cabin that covers the starter on the 582.

Ohh well so much for duck hunting this weekend .

Later fly safe all
