I have a petrol lawnmower but the cord completely jammed. I removed the cord/spinner assembly and fixed the problem but I’m not understanding how this assembly connects or operates with the motor. I initially was thinking that another cord or cable must run from the assembly to the motor in some way but there isn’t anything. If I just rivet back the assembly, will the mover work? I just don’t get how it all works.

There is no other cable connecting the pull-starter mechanism to the
engine. The pull-starter has a system where some type of fingers
grab when the cord is pulled, similar to what you might find in a
socket ratchet. After pulling, the fingers retract away. All that
is contained in the pull-start mechanism, which is then directly
connected to the engine.

It's a manual version of a centrifugal clutch.

The B&S unit has 5 fingers, 5 slots, and 6 ball bearings. When you
pull the starter cord 5 of the bearings will drop in the 5 slots but
the 6th ball bearing, not having a slot to go into, will jam between
the finger and frame putting torque on the motor shaft and spinning
the motor. When it starts centrifical force moves all the ball
bearings out of the way.
