Rough-idling 360, can't figure it out!

Buddy had me chasing timing for the longest time,wanted to replace ign control and refused to believe it was carb. Edelbrock 1406,i finally put my foot down and pulled carb apart. Bowl on one side was perfect, other side was green slime. I dont think i spent an hour on it, and didnt damage any gaskets. I like to put a thin film of grease on gaskets. May help seal and will come off without damage.
