What Is The Best Mini Starter?

If someone knows where to get parts for these, I'd like to hear. NAPA knows nothing. Last I heard, they were pretending to be an "auto parts store." I've got two that both have slipping clutches.

NAPA is about as good as you can get, and if THEY can't get service parts, it probably means they are not serviceable, but throw-away.
When the clutches begin to slip in these, is it a "maybe you'll start if you keep clicking",
or is it all over for the day and call for a ride?
