At somepoint i plan on buying my grandpas old hesston 220 sp swather and restoring it, my main concern is replacing all the drive belts and getting the engine running, its a wisconsin vg4d v4 gasoline air cooled engine, i think it will run if i get the old gas outta the tank and lines, from what i know it ran when parked, but i dont know how long ago that was, best guess is 20+ years. Any help will be appreciated.
