How do you figure ??? You don't just flip the engine and dump the contents on the floor when you're done !!! You use your head and with some small hose or tubing you siphon the fluid out of the cylinder. Tilt the motor slightly and properly position the hose and it should get just about all the fluid out. Jeez !!!
