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 the spring is set in the wrong position it can cause the engine RPMs to surge. Over time the spring can stretch out, causing the same engine surging. Often surging caused by the governor can be fixed by simply adjusting the governor spring. It usually only takes a small adjustment to correct the surging.
Among the potential underlying causes are vacuum leaks, EGR system malfunctions, malfunctioning oxygen sensors, dirty fuel injectors, fuel pump malfunction, faulty spark plugs, a faulty mass airflow sensor, or a faulty throttle position sensor.
Engine hunting and surging at idle is usually caused by a fuel delivery, air leak, or governor system problem. Cleaning/overhauling the carburettor, adjustment of the governor, and/or changing the air filer may be required.
Most often, over-revving occurs not because of a deliberate attempt to push a vehicle, but rather as a result of missing a gear while shifting. When a manual car accidentally downshifts, a rev limiter will not be able to react quickly enough to prevent the engine from over-revving.
Often this is a result of dirt buildup in the air intake. Other times it can be a problem with a cracked intake tube. If the IAC motor`s vacuum port is leaking, this can be another cause of high engine idling. The leak could be sourced at the seal, or more often, in one of the attached hoses.
RPM fluctuation is a common issue for cars with faulty spark plugs as they fire the fuel with the pistons. If they wear out, your acceleration slows, and jerking and misfire start occurring, which, in combination, causes poor fuel economy and vibrations.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
The problem may involve an annoying change (up/down) of engine speed while cruising at a steady pace, a low drop (or even cut-out) at idle or when approaching a stop, a wild high engine speed of several thousand rpm followed by a drop to near zero, etc.
Lawn mower surging is a result of either bad gas or spark plug, dirty air filter, or clogged gas cap vent. A dirty carburetor jet and fuel filter might also be the reason. You can also consider a carburetor gasket leak, which can be fixed by an engine starter spray.
The main reasons for an Engine Surge at Low RPM are Air, Fuel, Spark, and Compression which can be detected by the below indicators: Dirty or faulty mass airflow sensor. Clogged or dirty fuel injectors. Faulty spark plugs or ignition coils.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
If your car has high RPM while idling, it can be attributed to a problem with the idle control valve. This valve helps the car to maintain a specific RPM while idling. This idle control valve also has a fuse which if blown, will stop the valve from working altogether.

I have a Murray 6.0 hp 20 inch push lawn mower. How much oil do I put in when changing oil.
ANSWER : If there is a dip stick add some oil check the level till you get to the full mark. It should take a little more than a quart. If there is no dip stick then there is an oil fill plug down low on the engine. Fill slowly until the oil reaches the threads in the engine housing (almost overflowing). Be sure to replace the plug or you will have oil everywhere when you start it.

Don’t just dump the oil in, check the level as you go!
