As a comparison, my Homelite 30 was bought as a new shortblock in 1998. It is absolutly stock except for a WA167-1 carb. It has a Dynathrust 18-8 prop and turns 7400 rpm as shown.
I have another modified to the hilt and it turns a Classic 18-8 at 8200. It has C-H synchro spark ignition.

Enjoy,
Jim
