my 2001 honda 250ex. It ran fine up until about 2 days ago when I was riding it, it ran fine then about 2 seconds later it started stalling, it starts and I replaced the spark plug and made sure the wires are good. I’m not sure where those hoses go as well that I have circled or what that port is for on the side of the carburetor. It runs but as soon as I try to throttle up it bogs down bad, the air filter isn’t clogged. Any suggestions?
