The selonoid pushes the bendix into the
flywheel, there is a small plastic

fork
that does the pushing, to fix it you will
have to remove the starter, and have it
tested or test yourself with a battery and
a screwdriver crossed between the big
terminal on the little can, that's the selonoid,
and the small spade terminal, that's the
voltage that would come from the key.
You can watch the starter do it's thing,
but make sure you hold it tight, lots of
torque and it wants to spin on the ground
Good luck
