I searched the archives but couldn't find an answer to this. Does it hurt a single cylinder Wards/Clinton 1977 7.5 hp K751 if you turn off gas and run engine till it's out of gas? That's what I used to do with my Honda and Yamaha 4 strokes.
That's fine. It'll help prevent varnishing and gas won't leak out if you lay it down. There's usually residual oil leftover inside the motor anyhow. Make sure you're using a chainsaw/lawnmower 2-stroke lube.
