Yaksters;
Just got done adjusting the valves on my M14.
Here's the diagnosis.
All valves were within tolerance except for the number 3 and 7 cylinder
exhaust valves. The tolerances were tight....that is the #3 measured
.275mm and the #7 measured .280mm. Not sure if this could cause the
rough running engine in high altitude cold air I wrote about earlier.
A compression check afterwards showed normal and close to previous
measurements. I used the spec of .3mm +.15 -.1
A word of advice here, misadjusted valves could cause them to burn.
Used the silicone valve cover gaskets supplied by Doug Sapp and must say
they work great. Promises to stop any oil leaks from that area.
This brings up a question; How are the rockers lubed? I can see the
downward pointing cylinders were getting lots of oil but the upward
pointing cylinders seems to not get enough. Anyone care to elaborate?
Also, would it be beneficial if I modified my valve covers so that all
are connected together with rubber hose? Seems that some say this will
aid oiling or scavenging but I'm not entirely convinced.
Thanks in advance.

Evening everyone,
Well....My Yak 52 is ready for paint. Gosh...its been 11 months now.
First, I am in need of a few things. George Coy gave me the color numbers
for the DOSAAF red, white, and blue and I have missed placed them. I also
will need insignia for the nose and the rest of the aircraft, stars too. I
plan on using a self etching primer and need to know what works best? Not
planning on using Imron at all, by the way. My guy that sprays refuses to
use it.
Second, I need someone to check me out in it. I am at Lunken Airport,
Cincinnati. This should spark some interesting comments. LOL. I promised a
friend that I would have it up and flying in time for our local airshow in
September (Hi Steve and Donna!). I am trying guys. Been busy fixing the
Baron that bellied in. :-(
Blue Skies!

In theory, could the FAST organization forward a request for
blanket wavier (or exemption) to the FAA for purposes of
allowing FAST qualified aviators to overfly "densely
populated" areas in formation for the purposes of aerial
tribute appropriate to the occasion ? Having a copy of such
a letter in the cockpit, would allow flyovers and missing
man flights held in conjunction with local events. Certain
guidelines would apply of course, minimum altitudes, ATC
clearances when in controlled airspace, etc.
Yes, FAST national could forward such a request to the FAA. The chances of
the FAA granting such a waiver -- I would put it at a million to one, against,
and I am an optimist. If you are serious about such a proposal, I would
suggest that some preliminary work be done with the FAA to "grease the skids,"
as
it were, before a formal proposal is presented. Craig, perhaps you would
like to volunteer to carry the ball on this?
