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 :
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.
If the lawn mower engine produces black smoke, this indicates that the carburetor is getting too much fuel (or “running rich”). If the carburetor float is stuck open, the engine will get too much fuel.
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.
The most common cause of black smoke is a clogged air filter. Replace your mower`s air filter and this should resolve the problem. If you`re still seeing smoke, the air-to-fuel ratio may be off, in which case the lawn mower`s carburettor might need to be adjusted (ideally by a lawn mower repair specialist).
Translated into barbeque terms: white smoke is the sign of never-alive or nearly-dead fires. To counteract this, leave exhaust vents open to maximize oxygen intake to your coal or wood bed. This will increase the temperature of the flame and ensure your chosen fuel is fully combusting and creating only the good smoke.
White or Gray Smoke from Exhaust – Just like if you see white smoke from under the hood, persistent white smoke usually indicates a coolant leak. If there`s only a little bit, it`s probably condensation. Blue Smoke from Exhaust – If you see blue or dark gray smoke, that`s an indication of burning oil.
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.
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.
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.
If you have a riding mower like a lawn tractor and there is white smoke, this is usually an indication of excessive oil being added to the reservoir, or you may have a fault with the carburetor. It could also be a sign of a blown head gasket, but that is more rare.
“Smoke” coming out of your engine air filter is a symptom of a plugged Positive Crankcase Ventilation system. The PCV system takes unburned blowby gasses entering the crankcase and allows them to be drawn back into the intake manifold to be reburned.
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.
If at any point you detect the smell of burning rubber while the engine is in operation, discontinue use immediately. The belts that power the dethatcher mechanism are made of rubber, and this smell indicates that there is stress on the belts causing them to melt while the engine is running.
