...the more i think about it, that's probably caused by the intake valve opening and closing...

Eggzactlee. Your slide is vacuum controled, soooo it will flutter some w/ the valve

...next question...

..should it be able to open fully when gigging the throttle from idle??

I think w/ no load the vacuum would not drop far enough to fully open the slide.

What exactly are you talking about the slider fluttering?  The slider in the carb that's attached to the throttle cable?  What do you mean my by flutter?  I'm confused! ???

On a 4stroke the slide is vacuum operated.

I forgot to mention that the cable attaches to the butterfly. :)

Would the fluttering be caused by vacuum fluctuations being a single cylinder? I thought the more cylinders the more stable the vacuum.?
