My next door neighbor came over with a load of firewood. We were talking and he laughed about a mate of his whose wife brought him the fuel jug to fill the saw. He poured it in through the plastic spout on the jug and started it. Ran then died, and stayed dead.
A few days later he was trying to trouble shoot the saw, found water in the carb and when he poured out the fuel tank - there was heaps of water in the fuel!
He asked his wife about it and she said "there wasn't much fuel in the jug so I thinned it a bit with some water"
