Re: Interference Engines

["Pat Martin" <mardkins@email.msn.com>]

The crank pulley in the beater broke its key today and spun 180 out.  It did
not bend any valves at 65 mph and about 2/3 throttle.   Just got home about
1/2 hour ago after spending 8 hours finding parts and replacing it.  Why
does this stuff always happen an hour away from home?
