Re: [alfa] crank locking tool

["Jason Hagen" <hagen_jason1@xxxxxxx>]

As said before, rope.  Clean rope put in through the spark plug hole on the 
compression stroke so as not to bend a valve.

This works eveytime.  Just be sure to feed enough in to lock the cylinder.  
It's practically free.

Can anyone point out a deficiency with this approach?  I was surprised not 
to have been chastised for it yet...
