Hmm...No. The belt isn't too tight. I removed the belt and the pulley guard this morning, put it on a speed of "2" and held the servo pulley with my hand and started the motor. Sometimes I could prevent it from moving throughout the entire treadle range with very little force, other times there's tons of torque and I couldn't hold it at all, even in the ramp-up range.
Could I have received the only bad unit ever made?
