Post a pic of the motor with the cover plate removed, so we can see where you connect the power to. Usually the info you need is on the back side of the cover plate.
When I don't have the info I need, I take the motor apart. Look for the end switch. One of the wires on the end switch will go to the start winding and the other wire will go to a terminal where your 110v is connected, say L1. Use an ohmmeter and determine which wire of the start winding goes to L2. By reversing the connections of the start winding you will reverse the motor's direction. LOL
