Hi, drain and change the oil as it has become contaminated with fuel. This is caused by your carby flooding while stored. Check and clean the needle and float in the carby and make sure it stops fuel flow when you hold the float parallel to the carby body. You can also fit an inline fuel tap to prevent this happening again. Hope this helps, regards Phil.

Your lawn mower`s carburetor regulates the ratio of gasoline to air mixture. If the carburetor isn`t getting enough air, the mixture has a higher percentage of gasoline, which can create black exhaust smoke. It`s possible that a dirty or clogged air filter is preventing sufficient airflow into the carburetor.
In the majority of cases, a lawnmower engine suddenly bellows out blue or white smoke because oil has spilled onto the engine. The spillage can happen if you added or changed oil and slopped some or overfilled.
Overfilled oil reservoir: Too much oil in the reservoir can also cause a lawn mower to smoke. The lubrication systems in most mowers are not well sealed, and usually there`s an overflow oil reservoir with a relief outlet where excess oil can leak.
Oil Spillage and Leakage – If oil spills on the engine, it can burn and send up smoke without there being any overheating. The smoke will be blue or gray. Leaking Coolant – If you see white smoke under the hood, it`s most likely burning coolant that has come into contact with the hot components beneath your hood.
Smoke with a blue hue indicates burning engine oil. Engine oil can burn when it is far overdue for a routine oil change—or if you have replaced this fluid with the wrong oil type. Oil may also burn if you have a failing part somewhere in your engine, including a broken valve, leaking seal, or faulty piston ring.
If your engine oil is smoking, it could be due to one of two reasons—there`s too much oil in your engine or oil is burning in your combustion chamber. The best way to find out why your engine oil is smoking is to bring it in for service as soon as possible, as this could be a sign of serious engine damage.
This is usually brought on by low fuel octane, oil contamination in the air/fuel charge, or excessive boost or nitrous injection in high-performance engines. It can also be caused by poorly performed repairs, a clogged injector, clogged fuel filter, or a marginally failing fuel pump.
White Smoke
It usually means that coolant is being burned in the engine, which means that something is drastically wrong. The most common cause of this is a blown head gasket, which can quickly lead to an overheating engine.
To fix blue or gray smoke: The easy way is to add a bottle of Motor Honey Oil Treatment to your motor oil with each oil change. It`s specially designed to reduce oil burning and stop smoky exhausts. The hard way is an engine overhaul, which is about a hundred times more expensive and a thousand times more work.
Black smoke leaving your engine is often a sign that too much fuel is being burned. It could also be caused by a clogged air filter. If you catch either fault early, they are usually easy to fix.
White Exhaust Smoke
White smoke billowing out of your exhaust means that coolant is likely leaking into the cylinders. This usually happens when there has been a breach in the head gasket, which makes the coolant create this white steam.
The more serious cause of white smoke is engine coolant leaking into the cylinders. That can be caused by a cracked or porous cylinder head or engine block, a leaking intake manifold coolant transfer port or warped intake manifold, or a failing head gasket.
The most common answer to, “Why is my car smoking but not overheating?” is that there`s a type of fluid that`s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it`s burning off that fluid from the engine.
Without getting too technical, the injectors that deliver the fuel to the combustion chamber can leak or become stuck in the open position. This means too much fuel in the engine that needs to burn off and be expelled. This is seen as gray or white smoke from the exhaust.
White Smoke
In extreme cases, you will need to replace your head gasket. At the first sign of white smoke you can try head gasket repair treatment to seal the leak before you do serious damage to your engine.

When a mower is tipped over the oil has a chance to leak past the piston rings and coat the piston and valves. This will cause the motor to smoke until all the oil is burnt off, taking 5 minutes or more to stop smoking.
