Something I learned long ago, if you are looking at buying a non running machine, tinker with it enough to decide if it is an easy repair, but do NOT make a serious effort to start it. If it starts you have just cost yourself a good bit of money. I do not even try to start a non running rig to load it, just use my little cheap winch to drag it on to trailer and tie it down, then drive away with a slightly concerned look on my face, and once I am out of sight I smile.
If you are not part of the solution,
you are part of the problem!!!
