Why does my Arctic Cat idle but backfires?
It sounds to me that your carbs might be a little gunked up – you mentioned the gas may have been old, so it’s possible that the smaller (idle) jets are slightly plugged up. Fresh fuel might do the trick and/or you could try using a fuel system cleaner and water remover. This problem might ‘solve itself’ with a little time.
What happens when you give Arctic Cat 500 gas?
Arctic cat 500 dies when you give it gas but idles fine! It idles fine but chokes out as soon as you give it gas….no matter how slow or fast you try to engage the throttle. I have removed and cleaned all parts and jets in the carb (twice) and put it back together using the online diagram.
What should the idle be on a wildcat?
I found a screw on the left side of the throttle body, tightening it raises the idle, but loosening it does nothing, almost like the idle is set as low as it can possibly go already. I idle between 1250-1400 ish. Could be wrong here… not sure exactly what system is on the kitties.
What is the pilot jet on an Arctic Cat?
The pilot jet is a SMALL orifice jet (made of brass) in the body of the carb that regulates the flow of gas at idle and slower speeds.. it is crucial for acceleration of the engine.. if you do not know where it is/how to remove it/how to clean it AND its corresponding passages you will never get the carb “clean”!!

When to feather the throttle on a snowmobile?
You have to feather the throttle until the rpms are high enough for the clutch to engage and then the response is good. It only happens when you raise rpms from an idle. Gas is good, carb is clean, and I changed the main jet from 310 to 300. Any other suggestions?
