Are you talking about the pilot jets or mixture screws?
The mix screws can be adjusted with this method/tool (the Milwaukee Offset Screwdriver) very easily, with the right flat-head bit.

Swapping pilot jets can can be done without pulling the carbs. I did it, but you need a narrow-shafted, relatively wide bladed flat-head screwdriver that's no more than about 3" long including the handle. The usual multi-head screwdriver bits (hex-shaped base) are too wide to fit in the hole, so you can't use those or the MOS, unless you've got one with a blade shaft that's about an inch long (never seen one). Also you'll want fairly small hands, that can get in under the carbs to get torque on the screwdriver. I imagine it could be done with a pair of vicegrips on the screwdriver, but I didn't have to try. In short, it's doable, but you need to have a screwdriver of just the right proportions.

I realize this may be confusing but it's the best I can think of explain without pics, which I didn't think to take when I did my pilot swap about a year ago.
Here's the screwdriver I used, Craftsman 4-in-1 #45734. I got to the pilot jet with the wide-blade flat bit with the black extension, but not the handle.
