The slide on my carb is starting to get stuck in the throught of my carb. It was working fine I stopped riding cause of my leg and last night my son went to ride and the throttle was running wide open. He pulled the clutchand the engine dropped to normal . throttle back and she sticks wide open until he pulled the clutch. so I tore the carb off and cleaned it. upon inspection the slide starts going down fine then it just gets stuck. I am really confused. no damage to either part but sticking like it's gummed up. Any Ideas? Thanks in advance.
