I have a 2002 Rancher. I need to replace the choke cable and in getting to the carb, I noticed there is quite a bit of oil in the bottom of the plastic box that houses the air filter. Maybe an inch or so deep. Is this normal or indicative of a problem?

1st off make sure oil was not over filled at all it should be low if it has that much oil in air box over filling it could be the problem . 2nd any chance you have rolled the atv or put it on its side since last checking the air filter? if not i would say your pision rings are worn will have to pull top end to inspect rings ,piston ,cylinder worn top end like rings or cylinder will cause blow by past the rings and alow compression to past by rings and go into crank case and pump oil into air box through the crank case vent line
