After making sure that above rules have been observed, test compression of cylinders by turning propeller.
“DO NOT FORGET TO SHORT BOTH MAGNETOS”
Be sure all compression release and priming cocks do not leak compression. If they do, replace same with a new one immediately, as this might cause premature firing.
Open priming cocks and squirt some gasoline into each.
Close cocks.
Open compression release cocks.
Open throttle slightly.
If using Berling magnetos they should be three-quarters advanced.
If all the foregoing directions have been carefully followed, the engine is ready for starting.
In cranking engine either by starting crank, or propeller, it is essential to throw it over compression quickly.
