As in the message posted back to you - do the above. Pretty much the motors I have had in my car have been nice and smooth at idle, so if you have the motor running smick and it is shaking, I would check the mounts.
As for playing with the ignition and so forth, I would be giving this to someone else for the few dollars it costs. If not, buy a:
- timing light suited to the car (most are but helps to check)
- learn how to put the car into its "Self-Test: mode for checking the base timing. Very easy to do.
- Buy an extension (with a universal joint) for your socket/ratchet that allows you to reach the bolt that tighten the distributor (it is in a really hard to reach place).
- A good quality heat resistant glove that allows you to get your hand in to adjust the dizzy to advance or retard the timing.
Basic post here to make you feel as though people read the posts : ). Stay tuned to the site, you will pick up some good info out of here and also get to watch people slag each other off with Eric Estrada about someone being gay and so on....
(see "what's your current ride" for a fine example of what this board has to offer)
