I have a 2003 Arctic Cat 400.
Could not get the thing to run right and could not get it to not pour gas out of the carb. Didn't run for a couple years and attempted to rebuild a couple times. Never could get the float set quite right. Long story short, I replaced the carb (brand new one).
Starts up, runs pretty decently (though feels a little under powered, but it is so long since I have run it regularly, I don't have a good feel for it.
Anyway, it only runs with the choke on full, or 7/8. As soon as I drop the choke, it dies. It also seems to idle higher than it should. Has trouble getting in gear. It is an auto. I have turned the idle down as low as possible, so I feel like that is related to the choke.
Also, the regular ignition system has been disabled by a previous owner, just has a push button, but does need the key on to run. Is this going to impact the choke function at all?
So.
1. I believe the choke functions and I must have a fuel issue? In terms of not enough fuel delivery. But it is a brand new carb...is there an internal or external adjustment for the fuel mixture?
2. How does the idle speed relate to this?
3. I read that the issue might be a cracked boot between the air intake and the carb - unfiltered air causing issue?
