KR> Engine miss

[laser147 at juno.com]

I've had a miss in the secondary ignition for awhile and didn't know
which cylinder was missing.  I haven't been too concerned about tracking
it down since normally both the mag and the electronic ignition systems
are on and the engine runs smooth as silk.  I finally decided to address
this mystery today and figured it would be easy with my laser thermometer
to run the engine for a few minutes on just the secondary then see which
header was the coolest. I gave that one try but the result was
inconclusive, so I grabbed my Crayolas.  After the engine had cooled, I
put a few squiggles of orange crayon on each header next to the cylinder
bracket.  The unmelted orange crayon identified the problem cylinder
immediately. Using the thermometer laser pointed at the header bracket
where it meets the cylinders confirmed which cylinder was the culprit -
have no idea why that didn?t work the first time, but anyway . . . why
was that cylinder not firing? Was it the coil, the harness lead, or the
plug?
I took my Tiny Tach sensor wire off of its normal lead wire and wrapped
it around the lead going to the problem cylinder and then ran the engine.
I got an RPM reading on the Tiny Tach so that must mean the coil is
firing and the juice is getting through the lead at least as far as the
Tiny Tach sensor wire (but why is the Tiny Tach suddenly reading twice
the RPM it should be?).   So that left the plug as primary suspect in the
case. I didn't want to pull the plug since they were so nicely indexed
when I put them in . . . but worrying about that was pretty dumb I now
see in retrospect.  Maybe my days as a mechanic are numbered. Anyway, I
pulled the plug and put in a spare and ran the engine and it still had a
miss. So back to zero. I pulled the spare plug out and cleaned and
re-gapped the original plug and put it back in and ran the engine and the
miss was gone! These are Champion fine-wire 10mm racing plugs and when I
re-gapped it I found the gap was quite a bit wider than it was when I put
the plugs in 76 hours earlier. My assumption tonight is that it was the
excessive gap caused by wearing away of the electrodes that was causing
the miss. Tomorrow I'll pull the other three plugs that run off of the
secondary ignition and clean and gap them and also take an accurate
measure of just what the gaps are. Also need to look at that spare and
see if it is also got too wide a gap.   Are these green Great Plains
coils that sensitive to gap?  Are they wearing out and getting weak?  I
think they are motorcycle in origin and I've never noticed coils ever
wearing out on my bikes . . . .  I've put over 17K miles on my current
bike without ever pulling a plug and it's got coils under the tank that
work the same as the green coils on the 2180, so I'm not leaning towards
the theory that the green coils are wearing out, but it looks like the
miss was the result of too wide a spark plug gap and I would have thought
electronic coils could jump just about any gap they're presented with.   

I'm guessing the one I took out today was at least five thousandths over
what the specs call for which, with these plugs, is .016 to .019.  The
electrodes have lost a significant amount of material for the gaps to
have widened so much, but maybe that?s what fine-wire racing plugs do. 
Maybe they are designed to live short, hot lives on a track. 
This other issue that came up regarding the Tiny Tach readouts being
twice normal is a mystery I feel I should know the answer to but just
can't think of.  Nobody will be in their office for a couple more days so
I can't call Tiny Tach but maybe in the interim it will come to me.  Or
maybe I'll find the answer on the internet somewhere.  Or somebody
reading this will know exactly what's going on and tell me.  This Tiny
Tach has never done this before, but then until today I've never unwound
it from the lead it's been on since I bought it about five years ago.  
I've put it back on it's original lead and also played with the number of
times it's coiled around the lead, but nothing makes any difference.  It
continues to read twice as fast as it should.  The change obviously has
something to do with me fooling with the sensor wire.   Any ideas anyone?

KR> Removable turtle deck

[Dan Heath]

Removable turtle deck would be nice and could save you a lot in the future, but 
I think that having a removable forward deck is much more important, not to say 
that both are not a good thing to have as Mark has already shown that it is.  
However, I have never seen any other than Marks'.

 Does anyone besides Mark have a removable turtle deck or in the process of 
making one?

 I have mine attached with expanding foam.

KR> What are we doing this weekend? Pic

[Mark Langford]

What are we doing?  Friday I flew up to Troy Petteway's for a visit, and 
Saturday I flew down to my father's place, landing on his grass strip 
(see photo...runway is in the middle).  This runway is 80' wide and has 
a healthy downhill slant toward the bottom of the photo, and between 
that and the trees on the far end, it's something of a one-way strip. 
That works out fine though, because landing uphill really slows me down 
in a hurry. And even though I took off with a 12k tailwind yesterday, I 
was off the ground well before the halfway point.

  I've put 150 hours on N891JF this last year, and would have done far 
more had I not been swapping out wheels and brakes and sorting out other 
similar issues.  Last week I did a compression check and got within a 
couple of psi of 163 psi on all four cylinders.  Today I'm  doing some 
minor maintenance and hopefully cleaning up the hangar some.  Too windy 
to fly, or at least too windy to land on my narrow little runway! 
Tomorrow will be better though.

Gotta love the time machine!

I just had to go and do it again this morning. Just returned from a 2 hour 
flight. Smooth as glass up there. What a hoot. Never got above 3000? so that?s 
about 2000 agl up here. Keep building guys cause there is no better reward. And 
for those of you who don?t fly your finished KR. Why the hell not?

Robert, Fantastic ! Like you I've got about 8 years building mine and I 
am trying desperately to finish this summer. I take my hat off to anyone who 
has stuck with it long enough to finished an airplane. This is not an easy 
task. Life's circumstances can change a lot in 10 years. This is shown by all 
the unfinished KR's that are put up for sale. Again I say, Very proud of You 
and All who have completed a KR.

KR> Ballast weight installation

[Mike T]

So you no longer have a balanced elevator?  I know the plans only discuss
balancing the ailerons, but many people do the elevator also.  I assume an
unbalanced elevator must affect Vne, bit does it affect anything else? (And
I know of another VW-powered plane that balances only the elevator and not
the ailerons).
