Funny story. A neighbour's boy decided to fill his dad's mower up with water out of the hose one time. It did not run too well (at all!) after that.

So I wonder, in this case, could someone have poured in some paint instead of oil??? Could this have been the reason why someone decided to take it to the tip? Maybe they though it was too much trouble to clean paint out of a sump? Just me thinking out loud here!
