TR3 Spin on filter leak

[chammock@iquest.net]

        The TR3 got its first oil change a week or so ago.  I have the Moss
spin on adapter.  Long story short - the adapter screwed off with the filter
and now leaks some.  I can't seem to get it to stop.  Took off and checked
everything - put it back on and still leaks.  Any ideas or similar
experiences?  Can you get a replacment gasket for this thing?  Is it the
same as the canister gasket?
Thanks in Advance
