My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area.
Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

So I’ve got a 2000 Honda 400ex absolutely love it!! I’ve had it for about a month, I ride with bruteforce 750’s, outlander 850’s and 1000 sxs’s and I was thinking of getting a trx450r carb and a full hmf exhaust. And probably doing the air box mod too, how much power would this give my 400? Just a little different or a big difference? Cuz if it’s not much of a different I’ll just stick with my dg slip on..... thanks!

I hadn't driven my Kodiak for a two months, and since it was low on fuel, the first thing I did was filled it up to maybe 7/8 full. Getting ready to start it, I rotated the fuel selector switch to "on" and within seconds I smelled and saw fuel dripping onto the floor. I quickly turned it off and the fuel gradually stopped - I can repeat this.
The fuel is flowing from the hose that is connected to the bottom of the carb, and routes around to the left side toward the wheel well. Any idea what's going on here? It ran fine the last time I had it out.
Thanks...

I've been trying to piece this Lakota 300 back together, slowly. It's been a rabbit hole however. I replace one thing, then it leads to replacing other things. Anyway, When I got this thing I noticed that the hose coming off the camshaft cover wasn't attached to anything, it was just hanging loose. (It's literally just a foot long hose attached to nothing) I figured since it was venting the head it would be ok and I am sure it is.
However, last night I was looking at the service manual and noticed that it mentioned that this atv has a crankcase breather tube as well. Mine does not have one, so I looked at Partzilla and looked at the parts diagram and sure enough, it's definitely supposed to have one. The problem however is, the service manual does not show how it hooks up and the parts diagram only shows the exploded view of the assembly. I just find that kind of strange, nowhere in the manual does it show how it connects. Does it have it connector, attach to a nipple? It just doesn't say and it bothers me that there is a hole there without anything attached to it. If anyone has a Bayou 300 or Lakota 300 with an intact breather vent system and could possibly take some clear photos of it or know how it connects I would be very grateful. I have searched high and low and cannot find any information on it.
Thanks

If anyone is having issues with the Mikuni VM24SS carb, I thought I would post what issues I had and how I resolved them.
Acquired a 93 Bayou 220 that had sat for over 4 years.
The carb was extremely corroded and pitted and full of leftover fuel.
Cleaned carb and bowl and was able to get the engine to start.
Within 30 seconds exhaust would heat up and start to glow red hot.
Removed carb and recleaned everything, including a second overnight soak.
Needless to say, after removing the carb for the 5th time and my frustration to the limit I
realized that my attention had been to the carb body and not to the bowl.
There is a small brass rod on the bottom of the carb that goes down into the float bowl but is seperated from the main section. I had cleaned that area very well....I had thought.
***The corrosion had sealed off the channel that runs from the main bowl section to the small tube section on the side of the float bowl. No amount of carb cleaner was going to get it to budge. So i took a small nail and started to scrape away the corrosion and was eventually able to dislodge enought of the corrosion that carb cleaner would flow through that channel. ***
I thoroughly cleaned each side of the channel in the float bowl and reinstalled the carb and now the issue of it running lean is gone.
On a second note the fuel mixture screw was a nightmare to remove as the threads had been corroded and wouldnt let the screw come out. I used a little cutting oil and worked the mixture screw in and out until I was able to push past the corroded threads and completely remove the needle. After a couple passes with a tap to clean the threads it is like new again.
Hope this helps if you are having a lean running machine.
