KDX50 Won't Run

[theroyz71]

My son's 2004 kdx50 won't start without the choke on. With the choke on, it starts right up. Once it starts, I turn off the choke and it dies after a few seconds. I changed the plug, checked the air filter, and cleaned the spark arrester. The bike was running fine. My son took a break and when he went back out, it started acting up. Any ideas.

Yep... what he said.

Pull the carb and clean it out. All of a 10min process.
