Is this motor 1 speed or 2 speed? If it is 1 speed can it be made into a 2 speed? I hooked it up and it seems a little fast. It made a little noise so I drilled a 1/8 hole in the end of the motor and put a few drops of oil in and it quietened right down.

On the first switch position, power is routed through a resistor to get slow speed. Originally the resistor was located on the fan switch. A later update relocated the resistor to the engine side of the firewall.Restorations by Skip Towne

The original switch (with two resistors) is part #1540151. The new switch is part of kit #1547064.
