(Chances are, by the sound, your basic timing is retarded.)
Be sure that the vacuum advance hose is removed and plugged. And your idle speed is set fairly close. For a ballpark setting, set around 8 to 10 degrees BTC. Then connect hose and reset idle speed and idle mix (if possible).

If the motor will not run right at this setting, the outer ring of the damper may have rotated changing your timing mark.
If so, get back here and we will give you more information on how to get the right mark.

i made sure that the vacuum advance was plugged and when i get the timing mark to 10 or 8 degrees the engine will either idle so low that when i put it in gear it shuts off or it just shuts off. any other things that could be wrong?

Try raising your idle up until it no longer dies. Could be idle mix screws. You could have a number of things wrong. We need more details of what you were doing and how this began or when it was running good before.

ok when the timing mark is off the gauge like on the other side of the harmonik balancer the car runs better and when the timing mark is on the correct place on the gauge the car will die down and shut off or it will backfire.

It could be the outer ring of your damper has "walked' to a different location.
You can set the timing where it runs good..drive out on the road and advance or retard to the best place. Which I believe is a pretty good way to fine tune your engine to run the best. If it's sluggish, advance. If it pings, retard.

If you are new at this stuff, this may be easier than trying to find a new TDC mark.

If you really want to try it, follow this video from Summit. In addition to this, first remove your positive battery cable. Because on my vehicle, it was tight around the pulleys, I turned mine BY HAND SLOWLY using a screwdriver on the flywheel. DO NOT USE YOUR STARTER.
IMMEDIATELY after you set your 2 marks, pull out the piston stop and replace your plug and wire.
Once you have the new TDC, you can affix a timing tape for your size damper.
