Default Re: my second build.need advice on tunning

So I got my carburetor tuned right finally and runs clean and Smith through the whole rpm range. It just doesn't seem to have enough air flow with this carburetor. I have a different intake manifold matched the ports on the intake and exhaust and opened up the exhaust where it connects to the cylinder. I have read that the cns carb has a bigger opening and it had more fine tuning adjustments on it so here is the issue...........

I just picked up a used cns carburetor and I just fully I disassembled and cleaned everything and made sure everything was correct. QUESTION? ??? Where should i start out with the settings on this carburetor for the start. Clip position, air screw, and idle screw before I put it on the bike and start it up?
