Float level could be set wrong too. As far as I know the float level on the stock 400EX carb cannot be adjusted. There is no metal bar connecting the two floats together that can be bent for adjustment. The float is all plastic and would break if you tried to bend it to adjust it.

Poker client for mac. NOTE: When installing parts made of brass (the jets and needles), be very careful not to overtighten them because brass is a soft metal.
I just bought a 2007 400ex used and when I got the the previous owner had twisted the idle screw pretty bad and the quad was stuck idling kinda high.The quad had run wonderfully before I replaced the cable. Anyways, after replacing the cable I try to start it up and it wont turn over when choked. Then I turn the choke off it starts with much hesitation and when it finally does it sounds horrible with tons of backfiring almost popping/ grinding noises. I turned it off right away so that I didn't dig myself into an even deeper hole.
After that I checked the oil and it looked fine but the pipe was SUPER hot. I think it might be getting way to much air and not enough fuel. First off where is the air/fuel screw and which way should I turn it to give it more fuel? I've heard all the way in and 3 turns out is a good starting point but I really have know idea what I'm talking about lol. Thanks a lot any help would be greatly appreciated!

Hey everyone, having an issue with my bike and would like some input/suggestions.
I have a '96 fourtrax 300 4x4 which sat for almost a year. I couldn't get it started with a new battery, so I took apart the carburetor and gave it a good cleaning. Popped it back in and then it started with some choke help of course.
I then took for a ride down the road and noticed some throttle issues - basically seemed like it was starving for gas as I switched gears, which I was not getting the old power thrust I used to. I also noticed a different smell - not quite clutch burn though. Also, if I did not stay in motion, the motor would kill.
Two things to note regarding the carburetor cleaning:
1. When I removed the jets, I removed the idle mixture screw (pilot screw) without noting its original position, on accident. So I decided to place it back not too tight nor too loose.
2. I purchased one of those little $20 packets which contains a few replacement parts (ie: o ring, jets, springs and washers)
I noticed that when I removed my main jet, there was no emulsion tube in the hole (like stated in the instructions I was following) This tube was however in my replacement packet but would not fit below the main jet if I tried to re-install, so I left it out.
Any of you Honda gurus out there have any ideas/suggestions for this not so tech savvy bike owner? Would be much appreciated.
