Resistance rises as the filament (or heater element) gets hotter. This would be a problem with a load. I assume the motor will be run unloaded.
["rope start" the motor]
You (and Ron) are thinking Split Phase Induction Motor. His motor looks more like a Permanent Split-Capacitor (PSC). Go to the bottom of the page of this Wikipedia link .
I don't disagree that the resistor idea might not work very well, but his instructor has approved it. We'll go with it for now, unless he switches to the Triac controllers.
Either way, we'll all learn something.
