I just measured the cam gear and it is about 41.5mm diameter. The 30t gear in the timing cover meshes perfectly with the gear below it. I'm looking closer and I may be able to get another mm from the slightly raised magnets but they still won't touch. I think I found the problem. On the cam shaft, the bearings are sitting in indentations. I believe they may be sitting slightly high due to possible over extrusion . If I shave some plastic out it will sit lower and should then mesh with the gears. I will post here if that works.
