[Shotimes] Engine troubles

Sun, 21 Mar 2004 23:56:50 -0800 (PST)

The sensor casing was cracked and the whole thing
itself was pretty beat up. Looked like someone took a
hammer to it. I couldn't believe I didn't spot it when
I first looked at the engine before I bought it. This
was, of course, before I knew anything of shotimes or
anything sho-related online. The local parts stores
(well...the THREE that I had in MT at the time) didn't
carry it, so I paid dealer premiums...
