Technical HEEELP! 78 wont start

[margueritekrex]

I have a '78 Spider that wont start. We replaced the fuel filter, the pump appears to be pumping (manual). When it does start, it runs VERY rough and wont idle. It eventually dies even with my foot down on the floor bored. We cleaned the carborator with cleaner and with seafoam. My dad thinks it *might* be the selenoid?

ANY help pointing us in the right direction would be saving my life.

Thanks!

is it sparking ok?

Only one side is sparking. Do you think it's the points or the condensor?

start with plugs and work back, if there no spark at plug, check spark at end of lead an so on
