installing harmonic damper

FWIW, I rotate the crank to just past the bottom of the intake stoke on #1 cylinder, both valves should be closed. Remove #1 spark plug, and feed in about 18" of 1/4" rope. Slowly crank the motor over by hand, it should stop 20-30 degrees before Top Dead Center. Tighten the damper bolt by hand until damper (with pulley) is in the correct location. Reverse rotate engine, remove rope, and you're good to go.
