Goman, I posted links to two said clutch videos on this thread yesterday.
YouTube is great!
I tore apart the 4443 gear case this morning.
While the parts manual lumps the 4443 & 4447 together,
there are differences in the clutch arms and spring
actuator / retainer. I’m not sure the 4447 was
"new and improved" or not. 😮
The 4443 has a "long, half circle, "bail wire", thingy,
that hold the clutch arm up with tension. And instead
of a notch in the clutch arm (4447) that the shift rod
hooks to, the 4443’s shift rod has a blunt end that
pushes down on the clutch arm.
Overall, the 4443 gear case part are in better shape, and
the power head’s compression is somewhat better.
The 4447 will be a donor for cowlings, etc.
Have to investigate and see if any of the gear case seals
are available.
