The carbs need to be identical in all respects. The slide cutaway usually only affects throtlle openings below one third and usually works in conjunction with the idle circuit., and it is nornal to have main jets which are slightly too rich. THe thing you need to get correct is the needle jets and needles. When you lower the needles, you should be able to cause the motor to miss, then raise the needles one notch. If you cannot induce the miss, fit the next smaller needle jet. If the clip is in the bottom notch of the needle, you are either too rich, or you have run out of adjustment- need the bigger needle jet
