What's the axle length on your BB?
You'd be better off getting a longer axle to push your crank arm further out. I think those Miche BBs are only meant to be adjustable + or - 2mm?
You might also want to check your cranks, they might be JIS instead of ISO (look up on Sheldon) which I think means they would sit closer in on the axle which could be contributing to your problem.
