I'm ready to give this superstearman a shot, but i'm not sure what the cg should be, i've done some googling but cant get a definitive answer, other than the manual is wrong, some say measure from the bottom wing le others say measure from the top le.

Is there a way of finding out how to do it myself. I bought this second hand and it already has lead underneath the engine mounts, it seems to balance around a third of the top wing

If you measure the cord of the lower wing and add that figure to the amount that the top wing overhangs, (that is from the leading edge to the point directly above the lower wing leading edge) the total figure will give you the total root cord, from there a good place to start is 30% of root cord, measure it out on the underside of the top wing and see how it balances at that point, it normally tends to be about right and you can always make post test flight adjustments if it should be necessary.
