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 :
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
If you see a good spark at the coil, but not at the spark plug, then the problem may be caused by either a bad distributor cap, rotor, or carbon point and/or spring, or plug wires. Look down in the spark plug tube. If you see the spark going to the tube, the boot is bad.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
A Bad Crankshaft Position Sensor
The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.
Use Carburetor Cleaner
Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.
With a poor ground the starter ring return path may not allow adequate amps to return to allow a starter to reach the torque and speed to start. Normally, however, with a well tuned car and cranking, the engine will fire right up. Weakness, though, and it may not start.
If there isn`t any spark visible when kicking the engine over, follow these steps: (1) Check the metal cap on top of the spark plug and make sure it is tight. Give it a gentle twist with a pair of pliers if it isn`t. (2) Make sure that the spark plug lead wire is solidly connected to the spark plug cap.
Spark issues are the most common symptoms of failing stators, known as “Misfiring.” If you haven`t already known, stators are directly responsible for producing the required spark for your spark plug. Once they malfunction, the motorbike will receive insufficient – or worse, zero – sparks.
The PCM uses the signal from the crankshaft position sensor to determine when and in which cylinder to fire the spark. The signal from the crankshaft position is also utilized to check for misfires in the cylinders. There will be no spark and the fuel injectors will not operate if the sensor signal is missing.
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
