<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 face=Arial size=2>
