I have a 99' 300 2x4 arctic cat, that will not idle and when warmed up, I go to take choke off it stops running? only runs with the choke on. I did not use to be that way. To idle it up I see a cable near the carb with a philips head, but is stuck will not move, so I will have to replace. How hard is it to replace? Thanks for any infor

 

HELLO, HERE'S WHAT YOU WILL HAVE TO DO. I HAVE A 2000 MODEL 300 THAT WAS THAT WAY ONCE. THIS SHOULD FIX YOUR PROBLEM WHAT HAS HAPPENED THE IDLE SCREW HAS BEEN RAN ALL THE WAY IN, TAKE THE PHILLIPS HEAD ADJUSTER OUT OF ITS WIRE HOLDER SO YOU CAN TURN IT EASIER.YOU CAN DROP IT DOWN AND PULL IT OUT TO THE SIDE SO ITS STRAIGHT IN LINE WITH THE CARB BREAK IT LOOSE TURN IT TO THE LEFT 4 OR 5 TURNS START IT UP AND KEEP IT RUNNING TURN BACK IN UNTIL THE IDLE YOU WANT IS ACHIEVED. THIS SHOULD FIX YOUR CAT.
