It turns out it works very well for adjusting the pilot screws.

The end is tapered down, so it fits nicely into the hole, but it's still large enough to make use of most of the screw's slot (unlike a tiny jeweler's screwdriver) which makes it easier to turn. Being flat, it makes it pretty hard to mess up counting turns compared to a symmetric round screwdriver handle. And the whole thing fits easily under the carbs (which can't be said about a number of tools).

You want Dremel 90962 Collet Wrench. This is one of those things that will cost more for shipping than the item itself. The best deal I found was a guy on eBay who had bought a bunch (apparently he kept losing them) and decided to sell off the extras a few at a time for other people who always lose them. Obviously, you may already have one of these on hand if you own a Dremel.
