secondary throttle blade position

if you uncover the idle transfer slots on the primarys to obtain a suitable idle speed it will run rich and the idle mixture screws will be unresponsive, the secondary throttle plates have an adjustment for some reason.......you hit the nail right on the head....why else would they have an adjustment there???? Demon carbs have a very similar design and if you have instructions for a demon with or without the idle ease system you will find them very enlightening concerning the idle transfer slot's and responsivness of the idle mixture screws...the imformation applies to most carburetors...this is all just my opinion and I hope it is helpful to you

I have read a couple of times about carburetors that have the secondaries
adjusted to be slightly open on some applications. Is this to help improve the
idle on some motors with aggressive cams that have low vacuum or does it
help with an idle that may be too rich. A friend of mine and I were shooting
the breeze about this and would like your input.Thanks for your input.
