How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.
White smoke usually means coolant is getting into the combustion chambers of your vehicle. This generally happens because of a cracked or leaking head gasket, which allows coolant to seep into your cylinders. In extreme cases, you will need to replace your head gasket.
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.
If it`s clogged, the combustion chamber may not be getting enough oxygen, resulting in a too-rich fuel mixture that will cause the engine to run poorly and even spew smoke. The solution is to change the air filter, a relatively easy task. Blue and white smoke is the result of oil on the engine.
Spark Plug Issues
Examining the spark plug regularly is essential because a dirty one can cause various problems, and smoking is one of them. If the spark plug is dirty or too old, or if the plug`s gap is too large, it won`t start the mower and will sputter black smoke.
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.
Another symptom commonly associated with a problematic carburetor is black smoke coming from the exhaust. Black smoke coming from the exhaust is an indicator that the engine is running excessively rich, or using too much fuel.
Wynn`s Stop Smoke is an oil soluble supplement designed to reduce exhaust smoke due to oil burning. Applications: For petrol, LPG and diesel engines. For cars with excessive blue/grey exhaust smoke due to oil burning. Especially effective in older engines with worn components.
Black exhaust smoke
“When your exhaust pipe gives off black smoke, one of the things to get worried about are bad or worn out spark plugs. It means fuel burning in the combustion chamber is not being done 100 percent or burnt fully. It also means that air is not being well mixed with fuel to burn effectively.
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.
K-Seal can fix water loss and white smoke from your car exhaust. Thick white smoke pouring from the exhaust is usually due to a crack in the cylinder head, engine block or head gasket.
If possible, neutralize the unpleasant odor with an acid – like vinegar or lemon juice – or treat your space with vanilla extract. When using vinegar to remove smoke odor, you have a couple of options. You can mix vinegar and water and bring it to a boil in your microwave.
A faulty or dirty spark plug could be the reason your lawn mower won`t stay running. It might produce the initial spark, but the spark won`t be enough to keep the engine running if the plug is clogged with dirt and oil. Spark plugs are usually located on the front of a push lawn mower and connected to a black cable.
Overfilling a lawn mower oil tank will negatively affect engine performance and possibly prevent the mower from starting. Too much oil in a lawn mower can easily clog the air filter, foul spark plugs, and potentially cause a hydro-lock, which could bend the connection rods in a multi-cylinder mower.
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.
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 symptoms that your lawn mower has low oil include making knocking and spluttering sounds while running, quickly becoming overheated, thick black smoke coming out of the mower, an engine that flat-out refuses to start, and damage to internal parts.
Sign #2: You Can See (And Smell) Engine Exhaust
So if you see anything that looks like smoke, it could be a sign that the oil is old (if it`s not a sign of a major mechanical fault like a cracked head gasket). Ditto for if you can smell any hint of burning oil in your exhaust.
Stop Smoke Oil Treatment enhances oil viscosity providing a thick barrier that helps to seal gaps in worn engine components. With these gaps sealed the engine burns less oil, reducing blue smoke emissions and helping the engine to run more efficiently.
Black smoke is usually a sign that your mower`s engine is `running rich`, i.e. getting too much fuel and not enough air. The most common cause of black smoke is a clogged air filter. Replace your mower`s air filter and this should resolve the problem.
Another symptom commonly associated with a problematic carburetor is black smoke coming from the exhaust. Black smoke coming from the exhaust is an indicator that the engine is running excessively rich, or using too much fuel.
Your fuel is leaking, its not smoke, it fuel vapors caused by: too high fuel level, or the needle and seats (one or both are leaking) or leaking float, or too high fuel pressure.
