This is me eating crow. I reversed the motor and bingo. Thanks for the help everybody.
Many years ago. I was rushing on a motor change out. Fired up the new motor and felt air blowing out of the register on the supply plenum. called it good and left. 2 hours later, the customer calls and says the burner keeps cycling on and off. Went back, and found it running the wrong direction. Ooops. It happens.
