Yamaha F100 carbs, removed as an assembly (replaced the pilot jets. Made a tremendous improvement!):

The pilot jet is shown below (one pilot jet in each of the 4 carbs). There is a 4 mm hole through the center, much smaller than the holes you can see here (about the diameter of a bread wrap wire). Very small amounts of corrosion or deposit buildup can cause major problems. The difference in how it runs now is amazing!
