  [Regarding]: Paul Tackabury post and George Braly's reply.
  
  I think these are going off in the wrong direction.
  
  Lurkers and contributors have benefitted greatly from the SHARING of
  information here on the LML.  The engine set-up was purchased and George is
  under no
  obligation to provide us information about what he did (independent of  the
  fact that the LML may have sent much business his way) - Indeed, the
  purchaser
  "owns" that information and George may be obligated to not inform  others
  about what he did.  The "purchaser" may also have benefitted from  ideas
shared
  on the LML - maybe he is just a lurker and has chosen not to share  any
  information --- maybe not.
  
  Maybe someone else has tweaked their IV's engine installation and have
  produced results as good as George - after all, these are experimental
aircraft.
  And, maybe that someone would be willing to share what was done to improve
the
  fuel flow and cooling and .....
  
  I can't believe all the IV's, ES's, Legacy's (those powered by 6-cyls) are
  suffering from the same engine installation ills.
  
  Also, remember that if you are normally aspirated, not all inter cylinder
  fuel flow discrepancies are solely solved with Gami injectors -- there are
other
  ways.  If you have solved such problems with "tuned" injectors, remember
  that later changes to air flow and pressures in the cooling plenum may 
change
  
  the results.

  Hey George:  Regards your  baffle business for LIVs--you have made the claim
  that
  
  "every single IV-P's I have seen  were very poorly baffled and the fuel set
  up was improper"
  
  many times.  And of course  you always add that
  
  "I took one of these "stock"   IV-P's and fixed
  it.  It took a fair amount of time and effort, and a  lot of experience to
  know
  what to do and  how".
  
  OK, so you and  Gami are the smartest bunch in the world, but to suggest 
that
  you know a  secret that would provide all of us dummies building  LIVs a
  better engine installation and never share the details, well it  has become
  tiring.  If you want to sell this magic, offer it as a  product.  If you 
want
to be
  real helpful, provide a drawing.
  
  Speaking as one  who continues to refine my LIV engine installation, the
  Lancair provided  baffle kit seems a well thought out, good fitting
collection of
  bits of heavy  gauge aluminum.  Of course as is the case with all mysteries
  of air cooled engines and cowling drag, it probably could be  improved upon.
  
  So while my grinders and tin cutters are handy,  let me know what to do.
  Please do not wait until I publish my  performance numbers on this list and
then
  tell me I did it  wrong.

  Paul,
  I confess to having  written that message in language that was harsher than 
I
  would  prefer.
  Also, keep in mind  that I begged the owner of the plane that I fixed NOT to
  get me involved with  that project.
  I said I didn’t have  time.
  He said, “There are  lots of L IVP’s out there that need fixing.”
  I said, yes, but they  are all homebuilt aircraft,  and with only a few
  exceptions,  the  owners will simply copy anything I try to do or build, 
 and
so
  there is  no point in getting distracted from my other certified activities
that
  pay the  bills.
  e said,  “ how  long will it take.”  I said I don’t know,  but if I tried to
  do  it,  it would take at least a month or two to work it in with everything
  
  else.
  e said, “… how  much.”   I said I don’t know.   The owner then basically
  said,  “… here are the keys and I will write you a blank check. Please
  proceed, and let me know when you get it finished.”
  After it was  done,  successfully,   somebody on the forum posted up a
  message and said, in effect,  “heck, I can buy six new cylinders to  replace
the
  red hot cylinders that I am running with now,  for what that  cost.”     He
had
  a point,  if you want to treat the  machinery that way from now on.
  I can’t tell you what  to do,  because I don’t know what you have already
  done and what your  existing configuration is.
  e are not the  “smartest bunch in the world.”    I appreciate the sentiment
  if  it was sincere and if it was meant to be sarcastic,  that’s OK, because 
I
  
  probably deserved it for the blunt manner in which I posted up the  message.
  OTOH,  I have  spent the better part of the last eight years and a whole lot
  of money  studying this particular subject.
  What I do know is  that there is absolutely NO REASON why all of these 
planes
  should not perform  as well as the plane that we  modified two years ago.

  The point to my  message was to try to impress upon the owners of these
  wonderful airplanes  that there is a world of  unrealized performance in
these
  airplanes, and  they should not accept the status quo for  the indefinite
future.
  
  Regards,   George
