GA & OT meeting over successfully

Thanks to a desperate effort by the Executive officers, KMA Golden Age & Old Timer meeting at Uji Kyoto was over very successfully. We appreciate their contribution to the Special Meeting yesterday,especially do we Mr. Ymamoto who is the representative of Vintage division of KMA.
The applicants there are not always from near prefectures, but from Shimane, Aichi, Chiba and Tokyo.
Our friendly relationship becomes deeper and deeper, all are so kind and friendly as to make friends each other immediately after the first conversations. The time had passed like an arrow from early in the morning till evening.
I could have an opportunity to have a talk with a very famous in our field, Mr. Tetsuji Sato who is an original designer of control line model "Phoenix".
Talking about ENYA 20 TV that is one of my bad mood motor, immediately he pointed out the procedure of head screw tightening torque. Uneven and to much torque invites cylinder distortion leading to some bad operation condition. He put an emphasis on the point that ENYA 20 is very special motor that needs keen precise handling because of thinner and weak cylinder construction. Inviting 15 crank case and modification caused this inconvenient result. So, conventional and ordinary concept and principle should be forgotten when reconstruct this motor.
In addition, about an inconvenience on 60X Al-Chro motor that the stuck phenomenon between a piston top with inner edge of exhaust port and Schnuerle ports. He said that it is impossible to cause such a problem because the cylinder inner surface is finished after a relatively thick Chrome plating procedure, so no idea. Imaginable reason, someone in the process in dealing might do some thing wrong, fiddling.
As for my opinion on the problem, too much grinding might be done in lapping procedure causing narrower piston skirt portion forming and it invited slanting diagonally?
Any way, an experienced senior engineer such as Mr. Sato is indispensable person in our field.

I must declare very sad news, "Hornet" was lost and missing in a deep bush this morning just because of my trifle mistake.
I should have waited more 5 minutes before taking off till dens fog disappeared thoroughly,
It faded out into the dens fog immediately after P turn following to taking off.
It's a matter for regret to have made haste to take off early in the morning in the dens foggy circumstantial condition.
God gave me a warning against my Arrogant!
