Remove No1 sparkplug near the radiator and bring that piston to TDC on the compression stroke. Hold your thumb over the plug while a helper slowly cranks the engine until you feel pressure against your thumb. Once you feel pressure drop a long plastic straw on the top of that piston. Have the helper keep bumping the engine over as you watch the straw rise. Have the cap off and note the direction your rotor rotates.

Hal PS: Don't pull the distributor.
