Fuel/Water, Bearing/Rust

[vicenterc at comcast.net]

Just an idea for 2C engines:  What about turning the prop and position  the piston to top dead center so there would be no nitro residues and humidity going thru the pipe opening?  We will need to close the carburetor also.  I wonder if this will work.
