Bolens 17hp Garden Tractor flipped on it side and oil filled the engine cylinder. How do I get this cleaned up? Thanks

Drain the engine block via the drain plug. Remove the spark plug and turn your ignition key on for about 15 seconds, most of the excess oil is now out of the cylinder, spray in a little fuel and repeat. Cleanthe plug or install new, refill tank and crankcase, set to go.
