I keep fouling the plug on the passenger side. Is it just a matter of a bad plug, or what should I check for ? ? ?

I think one wire is longer now that I think about it. (See picture). So you won't be able to swap the wire from one side to another.
Does it use oil between changes? Blue smoke from the exhaust?

Did you ever resolve this issue?
Mine seems to carbon foul the right cyl(sitting on it). Just changed it for the second time in about 1.5 years. It will pop back through the intake under a load, when it gets to the point it needs to be changed.
Maybe I need to try replacing the wire on that side.
I've been using Champion XMD21 plugs.

My mule does the same thing except on the drivers side. In my case it is defintely gas fouling. It seems that a little too much choke when starting adds to the problem.
When the plug is cleaned, the mule runs great until the next fouling. I was planning to check valve adjustment until I remembered the hydraulic tappets. Looks like I will have to look into hotter plugs.

You might want to go to a hotter plug, some engines just won't run with the regular Autolite 2223, try the Autolite 2226 or Champion MDX-21. Also make sure your idle is not too low, should be around 800, plugs fowl at low RPM and you need to make sure you are keeping the air movong in the engine to keep it cool.

The hot plugs took care of my leaking ring problem from fouling out the standard plugs, a rebuild or new engine will be in your future,

another reason why the military gave up on the 4 cylinder engines and went 2 cylinder's FTW!!!( for the win)
ok getting back on topic i don't have this prob anymore i just made some adjustments to the carb and away we go... and a $1,000 engine rebuild helps and also hot plugs
