Yardworks mower: mixture setting

I have a Yardworks push lawn mower, model 11A-413B15-060-1603-6 which has what looks like an oily residue on the mower body. Is the carb mixture too rich and is the hexagon-headed screw a mixture screw? If so, how should it be set? Thanks.

I don't know what engine you have, but it probably doesn't have a mixture screw. If it runs good, it's probably not in need of carburetor work or changing the mixture. If the air filter is clogged, it will run rich. The oily residue is just something that happens after an engine gets old and several hours on it.

If it is a mixture screw, it should be turned clockwise until the engine starts to run rough. Then it should be turned counter clockwise until it runs smooth & at it's highest idle.
