RE: Do 2-stroke engines run clockwise
Tazzz,
Nearly any two-stroke engine will run in the reverse direction, for a limited amount of time and only at low throttle setting...
Opening the throttle over 20% will either stop the engine, or will make it 'flip-over' and begin to run normally.
The crankshaft port timing allows this... High timing numbers that support high RPM power, also allow reverse running...
Four-stroke engines may do this too.
