AndyMark Chassis Chain Clearance Issue

[gammabase]

After assembling the AndyMark 6-wheel drive chassis, we found that the chain from the Cimple box to the wheel was grazing the wheel by quite a bit. We've checked the instructions multiple times for mistakes, but so far it seems like we've done everything right. Does anybody else have this problem, or a solution to it?

We are going to try cutting and rearranging the white spacers on the wheel axle if nothing comes up.
