Question
I have a Dayton 1/4 hp split phase electric motor that will not
start unless you spin the shaft.
It does not have an external capacitor.Is there a capacitor inside
or what starts the motor?

Answer
No cap inside the motor.
There is a starting switch internally.
Take motor apart, and make sure the contacts on the stationary switch are not burnt. If so, replace the switch.
Otherwise, clean with fine emery paper, and make sure the rotating mechanism is closing the swicth in the stand still position.
I beleive it needs adjustment by bending the contact arms up a bit.

If the start wdg is burnt you will see it very dark or black , then replace the motor
