Removing debris will insure adequate cooling, correct engine speed and reduce the risk of fire.
II. Fuel Storage
! WARNING NEVER store engine with fuel in fuel tank inside a building with potential
sources of ignition such as hot water and space heaters, clothes dryers, electric motors, etc. Failure to do so may result in an explosion and result in death or serious injury.
