Fouling spark plug

OK, the choke cable was sticking some, and the nut that is on the end of the choke cable that screws into the carb. is broken. I was able to lube the cable, and with a little rigging, I was ablt to test run it. It is no longer running rich or fouling out the plug. I'm going to order the nut tomorrow. I also noticed that my K&N filter was extremely oily. I know they're supposed to be oiled, but it looks like it was dipped in oil. I cleaned it out with the cleaner today, and its currently drying. I will re-oil it tomorrow and go on a test ride. I will let y'all know how it goes.
Thanks for all the help y'all.
