Your last sentence there states the problem exactly- the chain links simply
aren't the right length for even stud spacing in many cases. Think about
it... the links fit over gear teeth, and why would the circumference of
integral-stud-diameter gears work out to even stud spacing?
According to the Ldraw version of the part (sorry, I don't have any links
here in my office to verify), they link 16 LDU apart. This equates to 4/5
of a stud offset, or 2 plates of distance. That means that if you are about
a half-plate too far apart... space the axles 1 stud closer to each other
and remove 1 chain link. If that's not quite enough, do it again. Or go
the other direction and keep trying different axle and chain spacing
combinations.
