Hey Lurk,
That is what I did! (your first sentence differs from your second, so I am going off what i read). When I did my short stroking research, the guides I used said to take teeth off the pickup side of the sector gear and teeth off the release side of the piston. This was to omit your exact reason of messing up the tappet plate timing. The guides that I used were as follows:

Are these guides incorrect in doing so? Should it be teeth removed from both the release side of the piston and the release side of the sector gear?
Thanks,
