I have one of the highly sought after YS624. Based on the plastic gas tank it’s at least a 1989 model or newer. It has been a work horse and runs but needs some TLC.
Asking $400 or best offer (serious offers only)
Electric starter is missing.
Have to play the choke upon first start, yet runs great.
May just need a new spark plug.
Maintained well with annual synthetic oil changes
Too big for my wife to operate, time to move on and get her into snow clearing :)
