The other day I decided to cut up some logs and wood scraps out back. So I drug out my chain saw, filled it up, and tried to start it. Its a little Homelite and has never been that easy to start. But all it would do was just sputter and stop. Long story short I somehow filled the oil reservoir with gas and the gas with chain oil. Anyway, I bet I spent an hour trying to start that thing. When I figured it out and drained it out and stuff and finally got it started I bet I smoked out the neighborhood.
