The ridges are only one the one case half, which made me wonder why they were there at all if not to restrict. The hole for the reedblock was the correct size for the pa50ii reeds. I was almost certain this was a 50ii motor I just didn't understand why they would bother making the nubs on this one case half if they didn't do anything
