Normal for gas to leak out when priming?

My carb leaks a bit of fuel when I prime it beyond four pushes. I have heard that's normal. Is it really, and why?

Yup, that's normal. Don't prime more than the book says, maybe try one less and see what happens.

Work fascinates me.

Getting back to my second question: Why do the bowls leak when primed?

because the primer forces air into the carb which forces fuel up and out

The gas is dripping from the carb throat, not the bowl.
