Aw man! You can do the timing. The light comes with 3 wires. Put the 2 with clamps on the positive (red) and negative (black) poles of the battery. The other wire goes around the #1 spark plug wire (front cylinder). Open the window in the bellhousing on the passenger's side that is located above the starter. Detach the hose (s) to the double diaphragm on the side of the distributor and plug them with a nail or golf tee. Loosen the 12mm clamp bolt that holds the distributor to the block. Make sure that the wires to the timing light are not going to be caught in belts or fan. Crank the engine and shine the light on the window in the bell housing. Look for a round dot (BB) or a line that should appear each time the light flashes. If you cannot see it, gradually turn the distributor. The motor will idle worse in one direction than the other. Keep looking for the BB, that is what you want to line up with the indicator prong. When you get there, tighten down the distributor bolt, close up the window, refasten your vacuum lines and remove your timing light. You are 7 degrees before top dead center on your ignition.
