Check for vacuum leaks?

 

^^^Seems like you have a vacuum leak...unmetered air finding it's way in.
This accounts for the uneven idle.

 

when you punch it does it flood? can be like mine dead cylinder due to broken rocker. did you do a cam? if you did was the piston to valve clearance enough? head work?
