Fuel/Water, Bearing/Rust

[michael Medlin]

I have been using rubber caps to plug the stinger on the pipe and also the
carb for the last year or so , and still get no more bearing life than
before. I mainly keep doing it to keep oil from dripping out.

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.
