Zilch, Nada, Nothing.
But I did have some kerosene taken out of a 5 gallon at the stick house a number of years back. I had left it sitting outside so I figured my fault. Shortly after that, the neighbors kids were having a heck of a time starting their snowmobiles. The snowmobiles were misfiring horribly and smoking up a storm. Took those kids several weeks to get those snowmobiles running right. Those kids have been extremely nice to me ever since. Nothing was ever said, and I had a heck of a good time watching those kids trying to get their sleds running right.
