Double checked everything today including that all the marks lined up at 0
degrees TDC.  Everything lined up on the second revolution.  I tightened the
crank bolt down tight like it should..about 115 ft-lbs.  And I think I found
the cause of the rattling noise... Two bolts on the engine damper were
loose.  So those got tightened down and everything seems back to normal,
except one thing... Maybe I never noticed ut before, but if you put your ear
near the exhaust it sounds like it's pulsating..anyone know why that might
be? Thanks for all the help everyone, with out you guys I'd be up that
famous creek without a paddle.
