MO Series
M Series Magneto – All B and M Group. For dynamo parts click here. The points end bearing changed from 35 to 37 mm outside diameter in 1940 and the diameter of the earth brush was reduced in 1955 from 6 to 5 mm. These magnetos could have the pick up on the left or right and the advance and retard cable could also be on the left or right (all viewed from the drive end). If the advance and retard cable enters on the right the ignition will be advanced when the cable is slack and vice-versa for a left hand cable. The pick up was always on the left but the advance and retard cable changed from the left to the right side in 1955. They are all described as anti-clockwise magnetos which refers to the direction of rotation again from the drive end. | |||
All parts fit all years of all MO series magnetos from 1936 unless stated otherwise. | |||
