Finally found the video on installing Ivan's jet kit. It includes adjusting the float bowls.
It's not a great video but it you can pause it and see what's going on. The key thing is the angle at which he's holding the bank of carbs. If you get the angle right, as you gently rotate the carbs the floats move, then stop, then move again. It's in that mid position that you need to make the measurement - not full in, not full out.
Bending the little copper tang is also fiddly, but doable. Good luck!
