Happened to be talking to a friend when I read this - who has work access to the Victa Portal. This is the result. There a a couple models listed with PT engines, all have same belt and pulley numbers available.
Since I haven't been following this thread, I am not sure if you have this info
But want to put this up quick since its 4:20 over there and you might be lucky to work it out before the stores shut for weekend
