Fuel/Water, Bearing/Rust

[vicenterc at comcast.net]

I remember reading the Mintor instructions.  The instructions recommends to run the engine with NO nitro if you are not planing to fly again for more than a week.  Also, I remember many years ago when I flew in Venezuela with NO nitro and we didn't have bearings problems.  Looks like we need to find out if Nitro is causing the problems particularly in 2 C engines with large pipes.  I think the nitro residues condense and form strong acid that attacks the metals.
