you tube how to clean a mower carburator.
Wash in gasoline.
Look at the engine on your lawn mower. If the engine has an oil filler tube or a "hole" with a cap on it where oil is added to the engine, it is a 4-cycle (4-stroke) engine. If there is no oil filler tube or place to add oil to the engine, then it is a 2-cycle (2-stroke) engine and the oil has to be added to the fuel.
The location of the fuel line depends on where the carburetor is mounted. If the carb is mounted directly on top of the fuel tank, the fuel "line" is the pickup tube that extends from the carburetor into the tank. The carburetor will have to be removed to get to the pickup tube. If the carb is mounted away from the fuel tank, the fuel line will come from the tank.
The intake is the tube that attaches to the engine - usually the carburetor is attached at the opposite end of the tube (intake).
If all oil the mower will not start. If only a little oil, the mower may start but run rough and smoke very much.
try you tube how to videos for small engine repairs
i would look on you tube for a instructional video, it's not very diffecult but hard to explain in words
For a walk-behind, I simply turn it on the side and let it run out of the oil-fill tube. Then about a pint will fill it.
It's just a small bicycle tire. Use a screwdriver or similar tool to separate the tire from the rim, remove old tube, insert new tube, add air.
Without the make and model I am just guessing. The oil fill tube is typically the highest point on the engine.
There isn't one! Honda asks you to tip the motor on its side, and drain the oil from out of the fill tube.
