I was fully aware killing the engine that way, was to help prevent rust. The thing I did differant was to rev up to top RPM and THEN kill engine....thus pulling in a lot more oil and gas. Like I said...done it over so many years I know it works. Those that do want to believe something simple like this can help, well its just to bad. I do not know if you ever cut wood in the winter, but I could tell the crap that was normally just collecting on piston surface and ports ...would just blow out on the snow (on start-up) and was very visable. This was not just a simple try it a couple of times...it was for over 20 years!!! Every month during the summer even, I started the chainsaws up bring up to temp...then flood em out. Did the same with G38 Zenoah and it runs very good. I had a guy say he never seen a G38 with flywheel ignition idle that slow. Regars Capt,n
