First, with spark plugs out, rotate the engine until the number 1 cylinder is at top dead center (TDC). Tighten the valve until only slight pressure takes up all slack. Then turn the adjustment nut 1/2 turn. Do the same for both valves. Now, rotate the engine 90 degrees, 1/4 turn of the crankshaft. Following the firing order, 1-8-... adjust each valve as you did for the number 1 cylinder. By grounding the number 1 plug with a wire attached to the engine, turning the distributor clockwise, and then turning on the ignition key, you can then slowly rotate the distributor countrclockwise until the spark plug fires. This should set the timing enough to start a freshly adjusted engine. Good luck!!
