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 :

The fuel and air will not mix as well as when your carburetor is balanced. This results in oil and gas spills from the exhaust of the lawn mower. The next time you see black liquid coming out of lawn mower exhaust vents, then this could be due to an imbalanced carburetor.
Gas leaks around the lawn mower air filter can indicate your engine valves are not working properly. If your engine has a fuel shut-off valve, ensure that this valve is closed when the engine is not in use.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking (partial or full) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.
An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
It is caused by excessive carbon deposits or engine sludge developing inside the crankcase. When the oil does not flow efficiently, excessive engine oil pressure will be created and cause extra oil to push through the PCV valve and into the air intake.
An overfilled crankcase and oversaturated foam air filter will also cause oil to travel from the air filter housing to other parts of the engine. If the mower produces black smoke, then it`s a problem if the lawn mower air filter is soaked in gas. The solution is just to replace the filter.
A choking sound is a common indicator of a engine not receiving enough fuel.
Manually – A manual choke is controlled by a lever on the side of the carb. A lever or knob inside the vehicle is then attached by a cable. This requires a person inside the car to slowly open the choke by hand. Automatically – An automatic choke uses a metal spring to open and close the choke plate.
Stale fuel, dirt, and debris are the most common cause of outdoor power equipment not starting or running properly. If you store equipment with untreated gas in the tank, it can lead to engine damage.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
Typically, there`s a 12:1 or 15:1 ratio of air to fuel, and when there`s too much air or not enough fuel, it causes sneezing or popping sounds in the intake.
Sometimes, your car may have the following symptoms: an irregular idle, poor fuel economy, lack of power, stalling, or a high-pitched hissing sound from the engine.
White smoke from your exhaust almost always indicates a blown head gasket, and just like there is coolant mixed with your engine oil, there will also be engine oil mixed with your coolant.
Leaky O-rings (spark plug tube seals) are probably the number one cause of oil on spark plugs. Spark plug tube seals keep engine oil, coolant, and everything else on one side of your spark plugs, so they remain dry. If these rings fail, engine oil can leak into your spark plug well and onto your spark plugs.
An oil filter leaking can damage your engine and impact your car`s performance. Ignore this issue for too long and it has the potential to become a serious threat to your vehicle and therefore your safety.
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.
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.

Oil that is a whitish milky color is contaminated with water, while oil that is a greenish milky color contains antifreeze. If the water is the result of normal condensation in the engine, the milky color will disappear once the lawn mower engine warms up.

I have a 7 hp B&G craftsman Pressure washer , if I place an air filter on it ,it wound’t start or run , if I remove the air filter it would run like a champ, but after 10 mints , oil would shoot out off the carb like a running faucet , why is it not running with the filter on,.Now am not so sure if the air filter is the correct size , because when I put it on it seem to be a bit on the taller size rather than a perfect fit, thanks for your help , in Hollywood , Reinaldo Roman .
ANSWER : First,It sounds like the air filter is full of dirt preventing air from flowing through, starving the engine of air.As for the oil shooting through, are you certain the oil is coming from teh carb?. Makes no sense the engine would run if it also shoots oil out the carb. There is nothing in the engine that would cause this, assuming it’s a gasoline engine. And I am not sure a diesel would do this either.

I have a husqvarna 137 chainsaw. The problem is with the bar oil. When the saw runs oil is flowing but where the rubber corner piece which allows the oil to flow out of appears to be just dripping the oil straight out. It looks like it should fill a small reservoir behind the metal plate and the oil then moves upwards where the chains drags the oil through the oil hole on the bar which is moving outwards as in the top chain on the bar. However the chain-brake area is just getting messy with oil splattering all over and the bar not actually getting oiled. I have fitted a new metal plate to see if the corner of the original was not sealing properly but that has not helped. The bar holes are clean. Any suggestions as I can’t see what it could be?
ANSWER : It’s the rubbers. I had the same problem with my 137 and 141. The rubbers shrink over time and the oil never makes it up the channel. The replacement part is one piece and less prone to leaking than the original 2 piece design.

Oil runs out air filter – Mantis 2-Cycle Tiller
ANSWER : If you have a fuel/oil mixture running out of the air filter, it is most likely you will need to service the carburetor. Today’s modern fuels will, over time, gum up the carburetors and small passage-ways within the carburetor making the carburetor ineffective. A carburetor rebuild kit can be a DIY project. Mantis has a very good customer service department that can locate your correct parts and send them inexpensively. The needle within the carburetor (behind the 4-screw plate on the carburetor) is likely not seating properly and the fuel is flowing through the carburetor and out the filter. Thanks!

I borrowed my nieghbors power washer. It worked the first day all day. In the morning i filled the gas with a fuel stabiler, and 30 oil. I may have over filled it. Upon turning it on the oil started leaking from the air filetr compartment. It starts, but then smokes starts to fume and all the oil leaks. Did I break it or is it a easy fix. I cleaned the filter housing. Also the filter was soaked with oil. should i get a new filter and install it or what is the solution. need help.
ANSWER : You will need to get a new filter, and drain some of the oil out of the machine. If you over fill these this will happen. 90% of the time nothing is broken.

My Craftsman 15 HP Lawn tractor is spewing white smoke. When I removed the air filter, I noticed there was oil all over the inside of the air filter and at the bottom of the air filter. When I run the tractor without the air filter covered I see oil being spewed up through the hot air vent into the carb. What could be causing this?
ANSWER : On ours ,it was a bad valve seal on the intake valve.If you have a way to air-lock the cylinder, (so the valve doesn`t drop), you can make this repair without removing the head.
