Flushing two-stroke engines: pour a small amount of kerosene into the combustion chamber through the spark plug hole and rotate the crankshaft – ATTENTION – ONLY AT BOTTOM DEAD CENTER - NOT THROUGH TOP DEAD CENTER. Pour out the kerosene, repeat 2-3 times. Then you can screw in the spark plug and carefully turn the engine past top dead centre again with a small amount of kerosene. Finally, unscrew the spark plug again and pour out the kerosene. We repeat once again – the ABC two-stroke must not be rotated past top dead centre without a spark plug screwed in!
