45 powered "Hornet"

All the traffics are crowded at all today because of the National Holidays continued 5 days, especially almost of the highway are occupied by automobiles everywhere like a axially extended parking place.
So, I make it a rule not to go out with my autos on any holiday wherever it may be even early in the morning, unfamiliar drivers would go unexpected direction without notice, go and stop actions also. Consequently, no possibility is desired to drive in comfort on National holidays.

Newly fabricated "Hornet" did not fly well even at second trial that is powered by YS 45 FR with fuel pressurized system. As the symptoms, slow to high control does not work well, finally stops though it works well on the ground before taking off. However well adjusted on the regulator the phenomena did not disappeared.
In addition, fuel drops from the carburetor, just leaking out! How come?
Deeper consideration and careful check led me the conclusion, leaking on one way valve or regulator, similar silicon check valve exist inside both of them.
Cutting residue of silicon material, very thin and tiny one, was found in the one way valve, caused pressure leak leading to lean mixture after a while.
However the new part it may be, careful checking must be done one by one  before assembling into a new craft.
It would be succeeded in stable operation next time like a proverb "Third honesty!".
