A distributor wrench can be a great tool to have from time to time.

As quoted from... me. heh.

Setting the timing on the car is very easy to do. First buy a timing light and an offset timing wrench. (The bolt on the distributor is placed inconveniently if you don't have one. heh) That'll run you probably no more than 40 bucks.
To bypass the computer, look for a tan wire with a black stripe on it on the passenger side of the car. There should be a bundle of wires helt together with some black plastic tubing, and sticking out of that will be the wire. It's got a plug on the wire, just disconnect that. (Do this with your car off.)

To hook up the timing light...

Put the inductive pickup on the #1 spark plug wire. It's the wire closest to the front of the car on the driver's side of the distributor. Then hook the positive cable to the positive terminal, then the ground to any good ground you can find. Turn the car on, and after a few seconds the check engine light should come on. (Also be careful not to let the wires of the timing light get anywhere near the belts or the fan.) With the car warmed up and at idle, point the timing light down to the marks. As you've seen, the marks are made up of a bunch of triangle shaped wedges. The widest "valley," towards the drivers side, is TDC. Then, the peaks, heading towards passenger's side, are 4*BTDC and then, I believe, 8*BTDC.

Loosen up the bolt on the distributor, and slowly turn it either way to adjust the timing: Counterclockwise to advance, clockwise to retard. Don't jerk the distributor as it doesn't take much to adjust the timing. Also, when adjusting the timing the engine's RPM's will vary, so don't let that throw you off. After you get the timing set, tighten down the distributor and check the timing again to make sure it didn't move. Then turn the car off, disconnect the timing light and plug back in the EST.

Hey Enk, how many times you think you've posted that man. You gotta have it on "keyboard speed dial" by now. Quick and simple though. Does the trick.

Re: how do i.....

Kudos for using the search feature to find these threads. Take back that Kudos for posting the same question in multiple threads.
To post your own thread (and you only need to do it once in the section that besy applies to your question) start in the section, say Tech/general engine, and click on the icon at the upper left corner that says "New Thread". It looks like a Camaro emblem on its side with a Firebird in it.

To do compression you will obviously need a compression gauge. Remove the spark plugs and screw the gauge in its place and crank the engine over.
Check the fluids. Smell the oil. Don't want it smelling like gas. Also look at the level. If its high then possible something has gotten in it. Also look for water and/or milky.
If an automatic smell the tranny fluid. Burnt smell bad. Looks dark, bad. That tranny if it works now will not soon.

Does it run? You can tell a lot by that if it does.
Put your hand by the tail pipes, do you hear a ticking sound? could be a burnt valve.

And maybe you should listen to you fiance. Might know best

if you don't know, nor have the tools

arrange for a shop to give it a once over before purchasing. It's $100 you won't regret spending. Emotions should not come into play when you are buying a car. THere is no such thing as a car that "you just have to have"
