Double check Neutral first. Many motor shops use the AC way of setting neutral which is not adequate. Grab your battery and bi-directional ammeter and get it as close to 0 deflection as possible.
Hey Tarth, can you explain the procedure on using this method? I never have had to go to this degree(our Westinghouse gennies are stamped for neutral plane and you can generally tell by your levelling speeds and im pretty sure the Otis ones are too)
Thanks in advance U.
