Still trying to determine why it's idling rough.
Completed vacuum leak check, carb solenoid, engine fuse, pulled the plugs, no problems there they looked good and clean, I'm at a loss...
Have you sprayed starting fluid or brake cleaner around the intake manifold ports while running?
If the idle changes in any way while doing this, you have a manifold leak or warpage.....
Near impossible to get a smooth idle under these conditions.
