FD440V Engine Surge--JohnDeere LX 178

16 year old John Deere LX 178 w/engine FD440V.
Engine has developed a surge, uneven idleing, at idle to full speed when under no load. Suspect the carburetor.
Under load engine seems to run smoothly but realize it's not.
Adjusted carb making slight change but still have problem.

Try running some SeaFoam thru it first. If that does not cure the problem, then the carb needs to come off, taken apart and cleaned.
