This is how it happened.I had it on the ground,started it up and it jerked backwards just a tad.
Then I picked it up and the tires was moving backwards,not fast,but was spinning somewhat.

So I turned it off so no damage would be caused to it,if it already hadent.
I looked everything over and all looked to be fine,Started it back up and it
was running the correct way then.I cant explain how it happened,I just know it
happened.

The other times was the exact way,started and it jerked backwards.
When I say jerked,I mean just a little jerk.I didnt keep it on long enough
to see what it was trying to do,for I feared it was messing something up.
Its running just fine now.I know it sounds weird,maybe even unbelieveable.

All the same it happened,and I was just asking if anyone has had this happen to
them,and why?
