First the motor will heat up in a hurry with the fan shroud off. The cooling air is not being forced across the cylinders. As suggested, check valves on other cylinder also and then plugs. You did not say what the model number is. If valves and plugs do not fix it, here is a SWAG. Some briggs twins have diodes in the kill wires of the coils.

It is normally .010 to .012 thousands.
