Given the information I would use 12. However I would temper the choice with knowledge of the load the motor sees and if it starts under load.

Well, a fellow at another group answered as below, so I had to get to Cardello's before 1:00 PM.
I went with 11 feet of the # 14/3.

. . . do I need to use # 12, or can I use # 14. Distance from outlet (20 amp) to motor will be about 10 feet.

Sounds like you're asking about cord, not building wiring. Typical thermoset and thermoplastic cords, like SO and SJO are rated 18A for 14 gauge (two current-carrying conductors, ground doesn't count) and 25A for 12 gauge.

Your call.

Come on. #14 is rated for 15 amps. Running it at 14.7 amps doesn't make sense.

If it was hardwired & not useing Romex + the motor having overload protection, 14 AWG is allowed to be considered as 20A wire. Cord & plug connected will have to use the normal more restricted rules.
