Well, since you are new at this. And the engine is on a stand. If I were you I would mark the balancer every 90 degrees, starting with TDC. [90, 180, 270]

Then turn the crank with a wrench, 15/16", till #1 intake valve closes and TDC lines up. There both valves are closed. Do your adjustment.

Then turn crank to 90 degree mark and adjust the the next cylinder in the firing order.

Do this eight times. Two revolutions of the crank.

When you're done, redo it to check.

Hope that helps.
