Sorry but split phase motors NEVER have capacitors.

Perhaps you would care to share with the us your current
source, their price and availability of a split phrase motor
that is equipped with a capacitor.
All capactitor start motors are split-phase motors.
Since you didn't follow my suggestion to go look up what a
split-phase motor is, allow me to elucidate:
A split-phase motor is a single phase AC induction motor
with a starting winding.
It doesn't make a difference if you put a capacitor in series
with the starting winding or not, it's still a split-phase
motor.
By convention we call the ones with a capacitor "capacitor
start", and by implication if we don't call it capacitor
start then it's resistance-start (or reactance-start, same
thing to all intents and purposes).
The alternative to a split-phase motor is a shaded-pole
motor, which does not have a starting winding.
