I have two of those, should convert like a ryobi, just trim the heck out of the back plate, throw on a ryobi long shaft prop hub (or make your own, the ryobi should be fairly close) all it really needs is a spacer to get the prop out far enough to have the nut on the shaft, then a prop washer, prop, spacer then flywheel, simple setup

only problem with this engine is the muffler, it's held on by springs and the outlet is the entire way around the thing, so you don't want it on a cowled plane or anything where there's going to be fuselage behind the muffler... unless you make a custom one
