Thanks Gary,
That really depends on how it was operated and stored.
If it has been operated properly and well stored at min you should change the fuel pump if not already done. THe original Pierburg was a great pump but after 20+ years the diaphragm and seals will be suspect.
You should change the rubber hoses if not already done.

Internals it is probably OK but check the magnetic plug and oil filter or you can yank a cylinder or borescope to be sure.

Check the Service bulletins: I ran your serial number and have attached a checksheet.
That engine had a stator replacement SB; gently separate/expand the shielding around the red wires going to the ignition modules and see what color the insulating sheath is: red is bad and the stator must be replaced. Black is OK.

I am sure to have missed some items so please chime in....
