No, normally they thread onto the crankshaft, then have a stud coming out that you mount the prop to with a nut. As I mentioned, yours is the long shaft engine, so you either need the long shaft prop hub, or you need to shorten the shaft, re-thread it, then you can use a short shaft prop hub.
Here's a couple of pics of prop hubs. One is on an Echo 58cc that I converted to CDI ignition, so it is made for use without the magneto flywheel. The other one is on a Homelite 30cc with a magneto. (Short shaft)
