When trying to start gas spits from air filter side side of carb. If I place my hand over air filter side and leave about 1/8 inch between hand and carb then crank it it will start but runs real bad. I give it throttle and it falls on its face. If I remove my hands it sputters stalls then backfires. It's getting too much gas. I replaced the carburetor​ and nothing has changed. Ive worked on mud trucks but for some reason this tiny little carb has me baffled.

      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 recently bought a 87 TRX 250 not running of course, the owner had a brand new Key Switch on it.
      I think it is the wrong one or wrong wire colors as the colors dont match up with wiring diagram i downloaded for it. 
      anyone have a pic of their ign switch wires where they connect with the wire colors for that model? I ended up leaving the black/w stripe and
      green wire disconnected in order to hot wire it for other testing but would like to know as the colors dont match diagram.
