Hey guys, my 97 yz125 is finally practically complete. Upon starting it up and letting it run, it leaks fuel out of this (I don’t know he correct term) hole? Vent? Lol. Anyways, what is this, why does it do it, and how do you think I can fix it? And yes there is a hose that is supposed to be on there.Photo

That is the overflow tube from the float bowl. Either you float level is set too high or you needle and seat are leaking.

Thank you! I will go from there. My friend tore the carb apart and put it back together for me. I’m sure it’s one or the other, most likely the float level.
