Hello Sean

Thanks for moving your starter question to the correct forum.

For the wind-up starters, they're only two types.
Yours is a Trip-Release (not an Impulse).
Service Guide No21 covers that:

In your wind-up photo, I can't the pawls are not visible,
suggesting that the alloy hub the pawls sit in is cactus.

Hope this helps.
