Hey guys just bought a 2007 yamaha grizzle 125 for my kid. The quad will start only on full choke and idle only On full choke. I can rev it up on full choke and drive it while the choke is open but if I close the choke at all it stalls. It will not stall if I'm driving the quad with the full choke and close the choke while I'm moving until I stop then it stalls. Is this clearly a carb issue? Thxs all I'm thinking of pulling the carb and cleaning but figured I post this first

 

Sounds like a carb problem to me. Make sure you pull the jets completely out and clean them good. I like to blow carb cleaner through them until I can see through.
