Internal mag timing on K4B

[dlp]

I took 3 mags a part to build one. Everything is good, I have fire, but I'm not sure about the internal timing. With the cam high sides up & down, I put the "c" mark on the fiber gear up on the right side of the bearing plate, just across from the plate retaining screw. I guess there is what I would call a "pointer" on the plate & this is where I set it. Is this correct? Thanks!

On the K,O,OH & FM4 mag for CW rotation facing drive end for like a MM yes you use the C mark aligned with right upper edge of bearing support plate while the mark or beveled tooth on rotor shaft gear is up pointed towards center of coil and cam in a vertical position with high lobes on top and bottom. For CCW mag use the A mark aligned with upper left edge for bearing plate and other gear with mark up. Set points at .020". FM,FM-O,FM-K,FM-OH mags were reversible in rotation but use different bearing breaker support plates, points sets and drive impulses to accomplish that. So make sure get or have the right points for a CW mag for MM.
