Hello jeshe0

I can't say I understand this at all.
The 4-stroke appears to have had two types of centrifugal clutches.
The 2-stroke had just one design.

My parts list in the Imperial record do not show the two-stroke chassis.
https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=72729

The parts list (below) for a 2-stroke shows no grub screw.
By unbolting the engine mount brackets from the chassis, the engine and clutch
flywheel should separate from the clutch drum and its output shaft. There is
no grub screw in the parts list I have.

The clutch flywheel and shoes should be released from the engine by removing
the clutch flywheel nut. Being on a taper, a simple mallet knock should release
the clutch flywheel from the engine.

Hope this helps.
