Nice thing about that system is that you never have to take the motor apart to service the starting system.........Rod.
Oh, I understand. Thanks for pointing the out, Rod. I suppose the issue is whether that's provided as a system. If someone just bought a motor I expect it would have to have a centrifugal switch just to make sure it would run. Otherwise, I suppose they'd have to provide a switch and that might not work in a number of applications where the motor is a replacement.
