Just follow Shadetree's instructions. Most ATV carbs work basically the same way.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Great write up, thank you for taking the time to share!

I have a 2003 rancher 350 4x4 (if it makes a difference). I just rebuilt the carb with a kit from Moose. I followed the online manual here (that is just a fantastic download).

Anyhoo the "pilot screw" on the bottom of the carb was set at 1 and 1/4 full turn in. I installed the new one at the same setting. My question does anyone know what the correct setting should be? After reading this thread I think I need to open it another full 1 and 1/4 turn.

Happy Trails

The initial setting for you carb is 1-3/4 turns out. That's just a starting point and should be close enough to start and run OK at that setting. After warming the engine up, just fine tune the adjustment until you get the smoothest idle. I usually just turn the screw in one direction until the engine starts to stumble and then I turn it the other direction until the engine starts to stumble. Count the number of turns in between stumbles and center the pilot screw in between. Some people will turn it out just a hair more to make it a little richer, but I always just aim for the smoothest idle since the pilot screw does very little over idle anyway. All engines won't have an exact setting, they will differ.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

thanks for the comment..as for your pilot jet screw..i hope you made sure you got all the old parts outta that tiny hole ??..sometimes it's a pain to get that tiny o-ring out..if you left it inside the carb..it will throw your settings out of wack..as for the turns out..helmut has you covered.
