there is plenty of good info out there but the main thing is to only work on one area at a time.
If you can get access to a wide selection of jets for tuning it will make it a lot easier and quicker (especially if you only need to pay for those you eventually "keep").
If you can find someone that knows these carbs and has a dyno, you will get it nutted pretty quickly but at $$, doing it yourself will take longer (but is satisfying and cheaper (maybe, if you don't blow anything up and don't have to buy heaps of jets !)).

Hope you can sort it out and good luck!
