Hi, my 03 400ex recently began leaking gas out of the carb drain even when the drain screw is seated. From reading online it seems like this is always a case of the float/float valve or seat. I disassembled my carb and cleaned it all out thoroughly. I checked to see if the valve would actually seal in the seat while I had it off the quad and it does. The float moves freely, there is no friction it doesn't bind anywhere, it appears to seat the needle at the appropriate time to my bare eye, when the float is down the needle isn't seated and when the float gets up to around level it seats the needle. I don't have a float gauge. there are no obstructions, debris, scratches or anything on the seat. Like I said I hooked up a little vial of gas to a tube and moved the float up and down and it would seal correctly. But once it's installed on the quad I can watch it, just idling, it will leak for like ten seconds, stop for maybe 20, leak for a minute, stop again...When I'm actually riding and it starts it will sputter and stuff as if it's draining too fast to even get into the jet. I tried adjusting the float a tad but I know it isn't really adjustable and don't want to break it. Is there anything else I could try other than clean it again? I wouldn't be posting if I hadn't already cleaned it 5 times with no change. Thanks

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.
