Rick, how many of us have a carb that is properly sized and could follow a general transfer slot size rule? I've found that transfer slots in general like to be exposed a very small amount, just enough to keep the circuit active at idle so that it immediatly flows when the throttle opens. Most motors like ours have a tendancy for off idle stumble unless idle were too rich and would usually want a stronger transfer circuit anyway. If the slot were too far exposed, it wouldn't have much to add to the transfer. I set my primary transfer slot at their ideal setting and then adjust the idle with the secondary butterflys, it's just luck that they come out with similar exposure to the primarys. Of course none of this matters for anyone else because my carb is horribly oversized anyway ;-)
