Ignition firing, firing order would be: Fire the two cylinders at TDC compression stroke. Fire other two cylinders at 180 degree crankshaft rotation. 540 degree crankshaft rotation without firing cylinders or firing the cylinders on the exhaust stroke. Bringing us back to fire two cylinders at TDC.
