Wife and i are cleaning out our pole barn and were bringing over some things to see if a friend wanted any of the stuff. Their mower died the other day. Our friend does not really know much about engines. The mower had gas didn't smell too bad but I figured I'd check spark. I pulled the spark plug and grounded it out to the engine, pulled the starter cord, good spark. Then I went back to fuel. I went through her vet supplies and got a syringe and I had a piece of tubing in the truck. Here are a couple of pics of what i found. Water Replaced the fuel with some two stroke i had in the truck. The mower fired right up. Saved her a trip to the small engine shop.
