Uneven idle/shaking in neutral

Hey everyone, just picked up a ST185 (1990) with very little troubling me after a thorough self-inspection.

One thing that is troubling though is a fairly uneven idle sound/sputtering, and the car shakes a bit when sitting at idle. The shaking seems to go away somewhat after a bit of warm up and some light revving, but will return.

A buddy of mine who's worked on several cars isn't worried by it, but I wanted to get the All-Trac owners perspective! I originally thought timing issue but, not sure I know enough about the car to car that for sure.

Thanks in advance.

My first guess would be that there is un-metered air getting into the engine. Look for loose or cracked vacuum hoses or intake hoses.
