Yes, John (UK) has a great set of instructions for doing this. I have a 202 and rebuilt the hydraulics earlier this year and used his instructions. I'm sure he'll chime in.
The adjustment you are speaking of which is supposed to have 3lbs pull is only for about the last 1/8" or so of travel for both levers. The position and draft controls have to be set correctly and the little cam has to be set properly as well before performing these adjustments. Again, John will probably email you his directions which explain it much more clearly than I can here as I've only done it once.
