The chainring seems to be slightly further out than the cog. I don't think a spacer would help in this case. It isn't off enough, IMO, to make too much of a difference. Less than 4mm from what it looks like. The cog is just a smidgen too close to the spokes from what I see. If the cog itself can be spaced further out, less than 0.5mm, that would be enough. The chain, in certain sections, 'clicks' against the spoke. This is my impression at least because the black coating of the spoke is wearing off. The clicking is not continuous when the wheel is spun and only happens at certain sections of the chain.
