<DIV><FONT face=Arial>Never thought about it, but it couldn't hurt. What got me
started thinking about it in the first place was the condition of a glow plug
after being in the engine over the winter. It looked like it had
stalagmites on it! As I recall, it was a piped .60 Rossi on a Curare. We're
talking a good 20 years ago, here. About the same time, I read an article about
nitric acid being a by-product of the combustion process of engines burning fuel
with nitro. BTW, all the other normal storage things had been done (run dry,
after-run oil, etc). My memory was a lot better back then so I stored that info
in my head and put it to use when the season came to an end. I did everything
the same and it was actually the same engine and pipe, except this time, I
rotated the engine up against compression to close off the exhaust port,
thereby shielding the innards of the engine from all those nasty fumes that
were reportedly lurking around in our tuned pipes. The following spring, the
glow plug and everything else was in good shape. </FONT><FONT

<DIV><FONT face=Arial>I've since read that the nitric acid thing was hogwash.
Don't know if it is or not, but I've been storing 2-strokes with the piston
closing off the exhaust port since that experience. Seems to help a bunch. Kinda
one of those take it or leave it things that I'm unable to discuss with any
technical expertise.</FONT></DIV>

<DIV><FONT face=Arial size=2>Verne,</FONT></DIV>
<DIV><FONT face=Arial size=2>that's an interesting suggestion. Would you
extend the thought to also make sure the carb port was a bit open, so the
fumes could escape harmlessly out the carb?</FONT></DIV>

<DIV><FONT face=Arial>Bob,</FONT></DIV>
<DIV><FONT face=Arial>This may sound a little crazy, but I learned in the
old piped-60 days to store my 2-cycles with the piston as high up in the
cylinder as possible. The logic was to close off the exhaust port
from all the nitric acid fumes in the exhaust system. The fumes seemed
to be worse in a piped system for whatever reason. Sounds crazy, but it
worked for me.</FONT></DIV>

<DIV><FONT face=Arial size=2>Finally got around to getting the Wagstaff
Extra airworthy, after not being run for the winter. Felt rough, so
tore it down. Bearing was not really bad, although a little rust was
present (wasn't a SS bearing). Upon investigation, noting the
serious lack of compression, I proceeded to replace the
bearing.</FONT></DIV>
<DIV><FONT face=Arial size=2> While the piston was out,
of course I cleaned it....lo and behold...RING rusted SOLID in the
groove. After careful working with my Amsoil spray, it freed, and I
cleaned the groove.</FONT></DIV>
<DIV><FONT face=Arial size=2> What was interesting was
oil on top of the cylinder, and on the cylinder wall (not a lot, but a
film was there)...and the side of the piston around the ring groove was
bone dry.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Fixed it all up, ran like a top, very smooth
- so shoudl be good to go. I have never seen a ring stuck like this
before, and just thought I'd share the tale in case anyone runs into
inexplicable roughness and low compression....</FONT></DIV><FONT
