I suggest that since the engine does run (though rough and spitting back) that you start with the basics before tearing in, I’m sure others can add a few more “non invasive” things to check before going in. You may get in there soon enough but observation, checking settings, and being METHODICAL is a sound approach to chase any problem, less expensive too…

The coil if looking leaky is certainly high on the list to replace, fresh gasoline alway a good idea after sitting

My list follows (choose the order and feel free to add items):

-are we getting good fuel supply? And air supply?
-sequentially pull each spark plug wire to check for idle drop and check for spark from each wire (inspect spark plugs and check gaps)
-inspect/(file)/gap the existing points (I’d use dwell meter if available) inspect rotor and cap
- use timing light to set timing (preferably one with programmable advance)
-compression check

After that I would probably pull the valve cover to check valve lash, and observe valve operation (when was that done last?)

After this I think you will have solid information, or questions….
