“Pass me the needle-nose pliers.”

Ron handed him the pliers without a word.

Nate lifted the brass float out of the housing, blew through the little main jet, and wiped a speck of black rubber off the tip of the float needle.

“Try it now,” Nate said, setting the tool back in the tray on the workbench.

“That just saved me a hundred dollars,” Ron said, shutting off the engine and setting his wrench down.
