Honda rancher carb/choke

2002 rancher 350.


First of all the rancher is hard to crank when cold. I have to give it gas and pull the choke and push it back in really quick.

Correct me if I'm wrong but shouldn't I be able to pull the choke out and it should just rev higher and continue to run? It will only run for about 1 second if you pull the choke out? What could this be?

I have cleaned the carb to no avail. I am thinking of just ordering a new one. Still has a little miss at idle and will sometimes shut off. I know it seems like I missed cleaning something, but I can tell you I have followed the write up on here and I am 99% it's all clean, maybe this could have something to do with the choke not acting right.

I have searched but can not seem to find any answers. Thanks guys.

Welcome to the forums! And I recently fixed this problem on my rancher, it's done that same thing for most of it's life.. What you need to do is tighten the choke cable, there's a rubber boot over the choke cable that you need to peel down, there's a tentioner under the boot that you need to tighten. Hope this helps you!

Thanks for the help! Maybe I worded it wrong.


For instance in the morning when it's stone cold I can get it to run by giving it gas and playing with the choke, but if I pull the choke all the way out it will not run at all, almost like its got way to much fuel or something. Instead of the choke enrichining (sp) it it just chokes it down, like it floods it or something, wish I could describe it better. Basically the choke is not functioning properly and I don't know why! Lol

Well, it still sounds a lot like the problem I was having. Did you try adjusting the choke?

Didn't know you could adjust the choke?

And take the plastic nut and tighten it.

Welcome to da forums... When you go to start it first thing,turn key to on,run switch to on,pull the choke all the way out,and hit the starter button,don't pump,or play with the throttle any,once it fires off,lower the choke button until it is idling a little high,but not way up high as it will flood the plug,and cause the engine to start bogging down,and eventually will fuel foul the spark plug...Install a new correct spark plug,and try it this way,and see if it doesn't work better for you...The "choke" is not a normal cut back on the air supply choke,but is actually an enrichener valve which adds more gas to the idle circuit which along with the timing not advancing at lower rpms will cause it to load up rather quickly,and start to fuel foul the spark plug if it isn't cut back down,or turned off soon...It should only be ran for a few seconds to a minute,or two at most,not 5-10 minutes...

Thanks for everyone's help it is greatly appreciated!

When I go to start it I turn key on pull choke all the way out, it stays there. I push starter button only and it only turns over and over.

Push choke back in and push starter button and it turns over a few times and finally starts but will shut off if you don't give it a little gas.

That's what I'm trying to say, the choke only aids in starting if while pushing the start button I pull up really quick and push back down immediately it will crank. But with choke fully pulled it will not continue to run, not even for a few seconds.
