Artic Cat 650 Prowler wont start

[fireman4074]

I have this 650 Prowler. It will turn over but will not stay crank. I have to keep priming it for it to stay crank. Once u get off the gas it will go dead. Also, the tailpipe and muffler turned cherry red while running. I put in a new spark plug and change gas with fresh gas. Has anyone experience this problem? I need some help.

I would say give your carburetor a thorough cleaning. If it runs with the pedal down, your main jet is clean & your idle jet must be plugged. Your idle jet takes over when you let off of the throttle. I have the same machine. Has it sat for any lengths of time?

 

[fireman4074]

Yes, it has been sitting for awhile. But what makes the muffler turn cherry red while trying to keep it running??

 

[dconine]

I'm guessing it's probably running lean. Lean running conditions will make the muffler turn red hot. Give your air filter & check & while your at it check your antifreeze.

The air filter and the housing is pretty dirty. I will try to get to cleaning carb tomorrow and let you know afterward. I appreaciate the input.

Your welcome. Good luck with the cleaning, just take your time and do everything right the first time. It's a lot easier than doing it twice

As suggested, your carb probably needs cleaning, and clean the air filter good and the box also. Also check to see if yours has a square black panel, about 4"X 6" back of the frame where the back of the seat sets. If so take this small panel off and (one on each side) and I think you will find a air filter there also. I am not sure if the 650 has it but the 700 does. (or mine does) I had a 650 and I dont remember seeing it, so look.

I have cleaned the carb out but it is still turning the tailpipe red. I cleaned the air filter and the housing out.

I am going to ask a dumb question. I assume you have checked the water and does the fan kick on?

Does this have any mods? Did you put in a jet kit? When was the last time you did a valve adjustment (if the manual states it requires one as standard maintenance procedures). I hear of this happening when someone puts a new jet in that allows too much fuel. Also make sure your exhaust is not clogged.

Does the plug look okay?
