I'll give it go....1st, find "Top Dead Center"...that's where #1 piston is at the top of its stroke, and both valves are closed....this should also line up the damper mark with "0" on the scale. Now move the dizzy's rotor to be firing the #1 spark plug....insert the dizzy into the engine, pop on the cap, and crank...should be close now and should start. If not twist the dizzy 'til it starts and runs smooth. Adjust timing with a timing light, if you have one.
