Te answer is that you are right. It can be done that way.

Another way is to balance the kart on an edge (say a bit of scaffold pole, the measure the distances from the axle centres front and rear.

A normal sort of distance is 1040mm so a kart with 50/50 weight distribution is 520 mm from each and one that is 40/60 is 624 from the front,416 from the back (and yes, 40% of the distance means 60% of the weight is at the back)

One of the advantages of the balance pole technique is that it very clearly shows you how far you have to move weights to make a difference. On a 1040mm wheelbase that means a one percent shift is 10.4mm.

If the overall weight of you and the kart is 160kg then you have to create a lever that has 1600 KG/mm of force. That's either 2Kg of lead 800mm from the point of balance or the 80kg driver 20mm.

It's also why it doesn't really matter where you put the lead you use for ballast on the seat, because unless it's a lot it won't make a noticeable difference. (and 10kg of lead on the back needs to be 160mm from the point of balance to make 1% difference)
