How to Identify and Fix Common Gardening Problems ?

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.
Black exhaust smoke simply means that your engine is burning too much fuel. Engines need both fuel to burn and oxygen to burn it with. If there`s too much fuel in the combustion chamber and not enough oxygen to burn it with, it can cause black smoke to come from your exhaust.
Incomplete combustion occurs and soot is formed when there is an overabundance of fuel (both diesel fuel and lube oil), insufficient residence time in the combustion zone, and/or non-availability of sufficient oxidants. Over-fueling is the primary cause of black smoke from the exhaust of a heavy duty diesel engine.
Causes. Incorrect amounts of air or fuel will cause the engine to run sporadically or not at all, as will a weak or improperly timed spark. An engine not getting the right amount of fuel, air or a proper spark will exhibit a loss of power.
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.
What causes lawn mower smoke (and what to do about it) 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.
Bad Oxygen Sensor
If your car`s O2 sensor is damaged, the air-fuel ratio will be off, and your engine may burn more fuel than necessary. A poor oxygen supply will lead to incomplete combustion, which causes an outpouring of black smoke from the exhaust.
Black smoke from exhaust
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.
There are several causes for your car to lose power significantly while accelerating. The most typical causes of a car not accelerating while driving include a faulty sensor, contaminated fuel or air filters, or a faulty timing belt.
The fix for this is to add a detergent additive to your diesel fuel on a regular basis. A multifunctional treatment like Dee-Zol will clean out the deposits, reduce the amount of fuel burned incompletely burned, and can even extend the life of your DPF (because less soot are being produced at any one time).
An engine misfire is when one or more cylinders doesn`t produce power, and there are several possible causes, from a fouled spark plug to a clogged fuel injector or faulty oxygen sensor.
The white smoke is the engine burning off all the excess oil. The fix – drain the excessive oil, and idle the engine until the smoke clears. This may take 5 minutes or so. Too much oil will cause other problems, smoke, poor running, no running, leaks, engine damage.
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.
