Artic Cat 400 4x4 Running rough
I recently bought a 2003 Atric Cat 400 4x4 and it was running fine when I bought it, all it needed was a battery. I put a new battery in it and it starts and idles fine and runs good until it warms up. When you give it gas it sputters and back fires but when I put the chode on about halfway it seems to run smoother when you're on the throttle but it won't idle. I'm not sure that its related to the battery or not. I'm thinking its a fuel issue but not sure. I'll check the fuel filter and drain the tank if I have to this weekend but just wondering in anyone had any suggestions.

CLEAN THE CARB.
Bad/old gas will varnish up the insides of the carb itself and crap from the fuel tank will plug up the jets.
If the machine has not been used for a while, or it's NEVER been cleaned - it's due.
I'd start by running some SEAFOAM thru the fuel system and replace your fuel filter (if it has one- if not add one)
It's not that hard to do, just take your time and pay close attention to how the carb comes apart so you can put it together again. Also be mindfull that the screws are SOFT and strip easily.

Good luck!

Turns out it wasn't even leaking from the bottom bowl on the carb but from a cracked fuel line that made it look like the bowl was leaking. So I replaced that and took the carb apart and cleaned it out anyway since I had removed everything to get to it and but it all back togather and it runs great. I'll be taking it out to PA to give it an all day test run.
