This is why a service history is so valuable when purchasing a used machine. It definitely enhances value and makes certain operations much easier.
Just a note for anyone else attempting to tune a machine with unknown history; Mixture screws that are in front of the center of the slide are fuel screws and turning out enrichens the mixture. If the screws are in back (engine side), hey're air screws and turning out leans the mixture.
It may be a pig, but it's a pig with a rocket in it's ass!
