The numbers should be comming down soon, as a good quater of them are about to be listed for sale (late model powertorques & 4-strokes)
It's quite a broad selection to, on the vintage side: Victa, Scott Bonnar, Rover, Turner, Toro, Bragg, Simplex, Rotoscythe, Boudy...
As you go through I can put aside spares for you, or would you prefer just a full spare engine?
