Yes, the alloy base is a completely different set up and your catcher wouldn't fit. The handles on the alloy mount to the side of the rear chute and the base is quite flat except for the final upsweep. Regarding one of your earlier comments, yes Rover did make a 2 Stroke utility, flat circular base like a Victa and used the Suzuki engine. I got the remains of one from the dump and fixed it up with an old B&S and flogged it at a local auction.
