It doesn't even have a timing belt and if it did, changing the valve timing certainly wouldn't help your problem.

Ok, maybe it isint the timing "belt" but the specific reason they gave me for not passing smog is the timing. This happened at my last smog check, and they just adjusted it so it would pass, but because it didnt run right after doing that, I asked them to change it back. Does this make sense?

I have no idea if that will solve your emissions problems and neither do they. The car would have to be tested and different things tried while it's hooked to the emissions machine. There are a number of different ways it can fail. There are 4 different gases that are tested.

I pulled out the paper work and it says it is the ignition timing the max should be 150 and it is 211.

No, it doesn't. There is no test for timing. It only measures the amounts of 4 different gases out of the exhaust.

You failed for 3 different things that I can see. Yes, your ignition timing is set too far advanced but you also have too much HC, and a check engine light on. You need some serious diagnostics.

Thank you Wrench, I do know those things are wrong and they are being fixed, however, I just wanted to know if there is a simple way to fix the ignition timing so that it will pass smog, whatever the last tech did 2 years ago to allow the car to pass took him 5 minutes, and I don't have the money for ALL of the repairs at once. So I know it is something fairly simple, I just dont know what it is.

Your check engine light is on. You WILL NOT pass until the reason for that light is repaired. Changing the ignition timing may also make the other readings much worse.
Unless you have a timing light and a way to read the exhaust emissions simultaneously, you'll likely make your problem much worse.

Here are the timing instructions anyway

SET IGNITION TIMING

The ignition timing marks are located on the engine front cover. A slot on the balancer indicates engine top dead center.

1. With engine RUNNING at operating temperature, choke fully open and air conditioning off, ground the diagnostic terminal of the ALDL terminal.
2. With the use of a timing light or meter, set timing at specified RPM, by loosening the distributor clamp bolt and rotating the distributor until specified timing is obtained.
3. Tighten the distributor clamp bolt and recheck timing to make sure the distributor was not moved during tightening.
4. With the engine still running, unground the diagnostic terminal.
5. Make carburetor adjustments as required.
