How do you fix a choke that is stuck open and won't close in 660 raptor?

To fix a stuck-open choke on a 660 Raptor, first, ensure the engine is off and cool. Check for any visible debris or corrosion around the choke mechanism, and clean it if necessary. You can also apply a penetrating lubricant to the choke linkage and gently work it back and forth to free it. If the problem persists, inspect the choke cable for damage or binding and consider replacing it if needed.
