What’s this hole (circled in red) for? Thank you.
The hole circled in red is a vacuum port passage (sometimes referred to as a pulse hole) that is unused and blocked off in the Briggs & Stratton LO206 application. I go more in depth about it here for anyone further more curious. Briggs LO206 Carburetor Flange Hole Explained (Walbro PZ22) – SwiftKarting
