"Hi larry, I read your other post.
As Kghost suggests, you should remove your distributor cap, rotor and check them and check the mechanical advance, sometimes the springs in there break or it binds up.
Rough idle can be poorly adjusted carb, dirty carb, bad fuel, bad spark plug(s), Plug wire(s), dist cap, rotor, worn dist gear, leaky intake manifold gasket(loose intake), loose carb, bad carb gaskets, incorrect ignition timing, worn or sticking valves.
If you dont have a manual you can download one, and If your not comfortable or able to check some of these things you'll need to search for some local help."
