timing?

i just bought a timing light, the instructions are not very help full, can some one give me a stept by step instructions, an i dont know wut im doing how the timing light work wut to point it at and what i need to know everything, thanks
 
The light will have a red and a black clamp that you'll attach to the positive and negative posts of the battery, and an inductive pickup clamp that you clip around your #1 spark plug wire (the right-front wire). The clamp is marked as to which way should face the plug, so make sure you have it on there right. Make sure all the wires are away from any moving parts, start the engine, and turn the light on. Point the flashing strobe light at the timing pointer just above the harmonic balance on the front of the engine (the main pulley on the lower front of the engine). The pointer is a little toward the left side of the engine, so that's where you want to shine the light. Read your timing setting on the markings on the side of the harmonic balance. They might be hard to see, so it helps to wipe some white paint into the markings with the engine off.
 
You do have a harmonic balancer, it's the 1" thick metal behind the crank pulley. The timing marks are usually coated with paint or gunk, you have to claen all that off to see them. I use white chalk rubbed on them to see them with the light.
