Honda 400ex Carburetor Float Adjustment

by guducciti1970 2020. 12. 17.


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.

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. Young jeezy inspiration 102 zip.
