Thanks Norm and BigTed so it has to be Powertorques, nothing else can be modified to make these fit?
Someone here in an earlier thread this year mentioned a way of converting the early steel decks, which took the full cranks, to take the PT (and therefore Briggs?).
You cut out the section of metal with the engine mounting holes out of the old rust ridden deck, to use as an adapter plate and graft it into this full crank deck. He mentioned that this deck with the different full crank hole pattern is made from thicker steel than later ones and therefore less prone to rusting through.
Wish I could find the link.
