YES this is exactly what im writing about. and yes i remove the plasic from the twistie tie. but i cannot get into that tiny hole, it is clogged badly. i dunno what to use cause the twistie bends and warps cause its too clogged. also any reason why two out of the four sets of carbs are either jetted or bigger needles?

 

that pocket drill looks baller. does anyone know what size that hole is and, how far do i go into it?

 

There is no documentation (that I've come across) as to why the jets are larger on the inside carburetors, #2 and #3. It is however documented that they are in fact different. As dyracuse pointed out, 138 on the inside 2 carbs and 135's on the outside carbs. I would figure that the inside carbs get slightly better air flow through them than the outer ones. Given that, they'd be slightly leaner. So, slightly bigger jets to adjust for it.

Make sure you're using the smallest twistie tie that you can find. This is the size of the one I was using. 0.0165" or 0.42mm.
