Could be lots of things. Could be plugs or wires or a combination of both are going bad. Probably time to change all of them any way.

SOURCE: my blazer runs good until

I have read that if the TPS is bad and you unplug it and the vehicle runs better then it could be the TPS.( throttle position sensor ). could also be low fuel pressure. also check or replace coolant tempurature sensor. if the coolant sensor sends wrong info to pcm when hot ,then it will throw the timing and etc. off. that could be why it backfires when warmed up. make sure fuel filter is ok!! have a good day !!

the first thing I would start with is looking for vaccume leaks. be sure to check your EGR valve, then move to your MAP sensor. The next thing that it could be is a stopped up catylic converter

I have a 2000 arctic cat 300 4x4, I have no problem starting her and she'll idle way until I give it some throttle then she starts to spit and sputter and I just installed a new carburetor.


was just working on a scooter with the same prob, turned out to be the cdi. I'd check other things before replacing that though. cracks in the intake boot, adjust valves, test plug and coil.

My arctic cat 4X4 with a Mikuni BST 31 carb suddenly lost power and fouled the plug.New plug makes it start instantly and it runs great for 10 sec then fouls plug.Diaphram is good. Bowl not leaking


Pull the carb off and rebuild it, it either has a failed fuel inlet valve or a sticking float or a plugged jet from dirt in the fuel. If you are careful you can do this clean out with no new gaskets, use carb spray and compressed air. You may need a new fuel inlet "Needle Valve and seat". If you do find allot of contaminates in the float bowl you will need to clean the fuel tank and lines to the carb.

The starter engages and starts the motor fine when the motor is cold. however if you ride and try to restart the starter just spins and you can only start using the kick stater.

2004 automatic arctic cat 500 atv with a keihon carborator - starts up and idles. drive and stop and it boggs down and stalls. try starting and it starts right back up. Any ideas?


sounds like it has been sitting, if you have never rebuilt a carb, best to bring it in,, the main jet is probably all gummed up,, you can try draining all your tank gas,, spraying carb cleaner into the carb after removing air cleaner but that really wont help out the main jet.. Stabil is a good product for gas if you are going to store your ride for awhile, it also acts to clean carbs while using a small amount when you fill up.

Have 1999 arctic cat 400 idles fine but accelerate it sputters and backfires. already cleaned carb


Hi Raymond,
This sounds an awful lot like a safety switch issue. A lot of ATV's now have safety switches which need to be deactivated otherwise the safety switch sends a signal to the ECU telling it to impede or delay the timing. So on your model I believe you have to pull the clutch in before you attempt to start it. AND you have an emergency brake safety switch. The emergency break safety switch can be activated if the emergency brake lever has been removed or if the pivot point is heavily worn, or if the rigging is wrong. All of these things will cause the lever to contact the switch improperly. And so your ATV thinks the emergency break is on. Basically your ATV thinks you're crazy for trying to accelerate while the break is on so it impedes or delays the timing so you wont hurt the ATV or yourself. And that's why your getting a nice idle but backfiring and sputtering when you try to accelerate.
Hope this helps. Good Luck
