1993 FI B2200 Cam timing Marks Adv Ret
 

I heard that the 1,2,3,4 cam sprocket on the B2200 is actually adjustable, but I can't find any info on the advance and retard degree increments each position is.
Any help greatly appreciated.

No kidding I didnt know that. But now that I study the picture I see the offset in the dowel holes and also the arrows oriented differently with the cogs at the perimeter. Interesting indeed!
