Slash, I just plonked a powertorque motor on the base and it fits perfectly so they must have fitted them in the early days. I think I have 3 of these bases with Briggs motors on them so I think I will put powertorques on them,I have plenty of those on rusted bases, turn them into a great mower. Be the best combination if the standard Victa catcher would fit. On really studying these bases it was a very complex casting and must have been very expensive to produce, easy to see why they went to the pressed metal bases
