The way to drain gasoline from a Briggs and Stratton lawn mower is to take the oil cap off and drain the oil. From there, run a rubber hose into the drain and siphon the rest of the oil and gas out.
There is no oil drain on a 650 series lawn mower. You have to turn the mower over and drain the oil from the spout you put it in the engine. Make sure the gas tank is empty
I pour it in holes, drilled in tree stump, to be burned.
Use the cold start button and check the oil and gas too
Only if it is a two-stroke (two-cycle) engine.
