Nikki carburetor 2019 Kawasaki Mule SX KAF400

This Mule has always run rich and carbon fouls plugs. It’s getting to where it will need rebuilding or replacing. Is there a replacement Walbro carburetor available for this Mule?

Might be simpler to rebuild the carburetor and install a leaner jet.

You have a choice of 99, 102, 105, and 109 that leaner than the 112 that supposedly was factory jet.

Or order a new carburetor and leaner jet.

Might be trial and error on which one to use.

That’s what I was thinking. I’m going to try a few more things in the morning. I’m going to recheck the choke cable adjustment. I’m going to pull the cover off of the mixture screw and see if I can fine tune it. If that fails, I will put a rebuild kit in it and smaller jet. I was hoping there was a Walbro replacement.
Thanks.

@StarTech
I think that I’ll order a #109 and #105.

put a BPR4ES spark plug in it. I've worked on several 600 series mules that fouled plugs, went up to BPR4ES from the stockc 6ES and that usuallys fixes them.
