Hi Petrulis,
Most of M2 mags i know of are Clockwise rotation looking from the drive end.

Hi Petrulis,
                  From a sectioned drawing in the 'Care and Maintenance' book for the 350 EW: the magneto turns in the same direction as the crankshaft - that is, clockwise at the drive end.

Hello All, Just a couple of observations for BTH Mags In most cases SV models use a point set with R for right on the points plate. OHV models use L on the points plate. Now if you are setting up a maggy from pieces or two models a right and left pick up ring must be used on the armature to match the points.Opinions differ on which way to use the advance cable (slack or tension advance) Some cam rings can be set for L or R rotation.
