Try taking the carbs off, removing the fuel bowl and taking out the pilot jet. Its a smaller jet right in front of the main jet, you may need to grind a screwdriver down to get to it unless you have a very small one. Chances are your pilots are plugged. Same thing was wrong with my 99 Z440 both pilots were gummed up. Good luck!
Hi and welcome to FixYa,
I am not familiar with Arctic Cats. However, with your indulgence, may I share a few ideas:
- if wetting the plugs with fuel would make the engine run, then fuel is not drawn into the combustion chamber. This may be cause by poor vacuum at the intake side;
- clogged/blocked jets;
- if the engine is a two stroke, there may be oil in the combustion chamber or too much in the bowl of the carb;
- you may want to also drain the carbs;
- check for presence of contaminants in the fuel specially water.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
