It does sound to me like a fuel problem Kerry -- sort of like starvation.
Are you using the milspec 6006 fuel lines? Then there's all the usual
things like fuel filter, screen, etc. Ignition problems generally are not
intermittent, IMO.
Good luck and let us know what the problem was when you find it.

I never installed gap seals, and my nose heavy Series 5 with an IO-240
has never been a problem to three point. Even when using 8.50's so the
only opinion I can offer is that for me at least I don't have any need for
them.
I generally land flapless, but occasionally with 1 notch. I can pretty must
tailwheel first the landing with no trouble.
So if you're building a Kitfox, you really don't need to feel like they are
an absolute neccesity (they aren't).

Lynn,
What part of California is your destination? There are lots of ways to get
through the mountains here. I 80 crosses West of Reno (N. of Lake Tahoe) at
an elevation of about 7200 ft, and US 50 South of Lake Tahoe at about 6500
ft. The trick is to cross over the saddles rather than the peaks. There
are also passes to the South with elevations that won't compromise your
limitations. I am not as familiar with those areas.
Incidentally if you are in the North - Sacramento area - you have a place to
stay here. We are in a residential airpark and your airplane will be right
outside your bedroom window. The same invitation to anyone else passing
through.
Incidentally again, our fly-in will be on June 9th this year. If that is
during your sojourne in California, you are more than welcome to join us.
you would, without a doubt, set the all time distance record. Check:

Hi Lowell-
My ultimate destination is up at Duane's place in Auburn/Newcastle.
I'll be coming by way of Sun 'n' Fun in Florida, then on to mid-
Texas, then California via whatever route is the easiest/lowest
elevation, based on my restriction of 10,000 feet MSL (give or take a
couple of feet if nobody's watching).
Hey, I might just stretch the stay in order to attend the Cameron
Park Fly-in...does the "long distance award" allow for such trips as
this, or does it have to be a "purpose" trip? : )
Get the lawyers working on that one, and get back to me. : )

<kerryskyring@hotmail.com>
We now have about 10 hours on the new 912 ULS in the S5 Kitfox.
Intermittently it will not reach full power, beginning to run rough at about
4,400 revs and not going over 5 thousand. Seems to occur mainly when the
engine is getting towards the upper limit of temperature during ground
running but has also occured during normal temperature in flight.
It will run normally delivering full power and then, after 15 minutes or so
this problem arises and then disappears again. A little unsettling. Because
it was intermittent we suspected spark but have changed ignition boxes,
cables, plugs and it remains. We are beginning to suspect carburettors and
perhaps mixture at this particular rev. range. Does anyone have similar
experience that might help us eliminate this? Thanks in advance.

What about vapor lock? All fuel system parts FWD of

anything near the exhaust? You could be boiling the

Not sure the age of the engine but check the

I am now flying my new Kitfox 5 Vixen again after waiting out the Wisconsin
winter. Seems to run and fly well but the water temps are running close to 200
degrees. Is this normal? Also the exhaust gas temps seem very high. What
should be the best operating temps for water, cyl head, egt, and oil for the 912
UL?
Thanks
Mark

180 is the lowest I will let the the oil, head, and water go. Highest is 220,
but I hear the oil can go to 300, not sure I want mine going that high. I think
my egt goes to 1475.

| Subject: | Re: Kitfox With A Vair In The Air |
John: Thanks. I have a S5 1550 TD. There were no weight and balance
problems. The Corvair engine is slightly lighter than the EA 81 was
when I included everything that was needed to make it work. 936# CG
9.59 With the Corvair installed complete the total aircraft weighed 17
pounds less. I added strut fairings and wheel pants which brought the
weight to 936.5 CG 10.29. I could have moved the engine forward a bit
more, but not bad. I have two batteries in the tail 17.5 lbs each that
can be moved forward to the rear of the baggage bag. Let me add here.
I would tried to build it lighter if I had known how.
Today I opened up the bottom cowl to alow more airflow, and swapped out
the oilcooler.
Changed the oil and filter. If the weather permits I'll see what more I
need to do. She flys great!
Its a good match.

as to whether it's possible to balance the Vair on the KF fuselage. Is it
a tri-gear or a taildragger? Any special weight & balance problems? You're
not flying with several pounds of lead on your tail? The Kitfox group is gaining
a new subgroup. 164 cu in. direct drive 110 horsepower. We'll all be interested
to hear about your performance figures. Just in the last couple days someone
posted, asking about alternatives to Rotax power. It will probably be of
interest to this group that the Corvair can be acquired and completely rebuilt
for approx $3000. Great work, Norm. Stay safe and fly smart. John
