[ARC5] Environment - unexplained effects.

Unexplained effects
Leslie's comment reminded me of this story.  When I was a kid mechanics Illustrated magazine had an auto repair advice column.  There was a man who had a problem with his car refusing to start but only when he stopped on the way home from work to buy ice cream and only when he bough butter brickle ice cream.  He never had a problem when he bought vanilla or chocolate.

Turns out  vanilla and chocolate ice cream was available in a box in the freezer, he only had to pick out what he needed while butter brickle had to be hand packed into a box which took additional time.  In that extra time the thermostatic choke reset and stuck so the car refused to start.

Great story I hope it was true.

I have no idea what affected the hay mower.

  Hmmm.  Well, about 40 years ago (the topic is now environment, not
  ARC-5) I was a farmer.
  Local wisdom precluded doing certain things when an east wind was
  blowing.
  Part way thru studying maths and physics, I regarded this advice with,
  (how shall I say this) - some caution, perhaps even quiet amusement.

  One summer I was mowing (hay) and the shuttle mower was just cranky.
  The overload kept tripping, and I had to 'back-up' constantly to
  re-engage the mechanism.
  I didn't get much hay mowed.

  That was before lunch.  After lunch, exactly one hour later, using the
  same mower, in the same paddock etc, the mower ran sweetly.
  I noticed the wind had swung 180 degrees - from east to west.  
  Sometimes environment DOES affect "things".
  That's all I can say ... except I certainly don't understand how the
  wind could affect the mower.
