My father in law has a artic cat 300 4x4 it's a 1999 has the low medium and high range selection. Any way he has rejeted, checked floats, adjusted the needle, etc. and the darn thing still runs like crap. He thinks he got a bum carb.

Any suggestions would greatly be appricated.[img]i/expressions/face-icon-small-smile.gif[/img][img]i/expressions/face-icon-small-confused.gif[/img]

Check the carb hose running from the carb to the head. This pulsates and will cause pin holes there for taken in air!. This has been a problem for several

 

When i took my carb apart i took the needle jet out also. You might want to check it if you didnt remove it the first time.

 

Thanks guys i will relay the messages to my father in law. Really appricate it!!!


Thanks again.[img]i/expressions/face-icon-small-smile.gif[/img]

 

On a role tonite, why stop at the other thread.
Needle In
Needle Out

 

This is gonna sound real stupid but.... it will acutually run with out a needle? You would have to have one small jet wouldn't you?

 

Hmm im not 100%. I wouldnt think so. But it might idle, and if you punch it it might. But the needle helps fuel/air delivery at all throttle ranges. Even WOT i think, the fuel/air still has to pass by the needle at WOT. I could be wrong, im far from an expert.

 

yamaha, I know your just trying to start something, but this is not the place to do it. He is trying to get help from members who actually care. Unlike some people who just try to start stuff because they don't actually know anything or have nothing better to do. I see that you have made the same post in several threads in the Artic Cat forum. Why don't you go someplace else? Unless your going to be constructive why don't you keep your comments to yourself. This will be the first and only time I will ever reply to one of your pointless posts. thank you
