what is this gizmo on the front bowl? i'm guessing it vents to the intake when the throttle is opened. and i'm never wrong, often mistaken. i bought it for the 350. View attachment 237709
I cant see your pic but my 800 spared bore has what I assume to be the same vent on top. A little arm the pushes down a "button" when the throttle is open. My little arm broke off after 4 or 5 times taking the bowls off to change jets and it hasn't affected performance.
