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 :

You should see a strong spark between the tester`s terminals when the engine is cranking. If there is no spark, this indicates that the spark plug is defective and should be replaced. Need help finding your model number? The carburetor might be clogged.
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.
In addition to fuel obstructions, a spark plug with an improper gap or one that is loose won`t sustain combustion. A broken flywheel key — the part that generates the charge for the spark plug — from wear or impact, can`t support combustion.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
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.
When couples say they no longer feel a “spark,” it may mean that they`re missing the initial feeling of infatuation or that long-term commitment has become challenging. Meeting your partner and falling in love may have felt exciting, new, and intense. You might have felt that it was the only factor in your life.
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90% of spark plug damage claims are due to improper torque. Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
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.
The low voltage primary circuit operates at battery voltage (12 to 14.5 volts) and is responsible for generating the signal to fire the spark plug at the exact right time and sending that signal to the ignition coil.
What kills ignition coils is location; being mounted in one of the hottest, most vibration prone and dirtiest parts of the engine. Modern ignition coils are typically located between two camshafts on the valve cover and exposed to dirt and oil.
A failed crankshaft positioning sensor can cause your engine tp have no spark. In most modern ICE engines they all use electronic ignition and engine management systems. Theses systems depend on the signal sent from the crankshaft position sensor to determine what cylinder is coming up on top dead center (TDC).
Soft, black, sooty dry deposits on plug indicate carbon fouling. Carbon fouling is an indication of a rich air-fuel mixture, weak ignition, or improper heat range (too cold).
The most common problem with spark plugs is the build up oil and carbon that dulls their effectiveness. Now, some of this is unavoidable and the natural course of a vehicle`s life, but things like the overheating of spark plugs from an incorrect fuel-to-air ratio can wear out spark plugs faster.
Do your best to listen for a “click” noise. If the click is strong and loud, it most likely means the solenoid has enough power and is working properly. If the clicking you are hearing is quiet or repetitive, it may be that your solenoid is not strong enough or does not have enough power from the battery.
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.
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.

Kohler engine 15.5 turns over but will not start
ANSWER : Hi hoho641…

Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting fire at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one.Make sure you are using fresh fuel.If the moweris over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
After you have the carburetor rebuilt that should solve you starting problem.

No spark at plugs after replacing coils it has spark advance what do I look for next
ANSWER : Check for the switching pulse at the coil input terminal. It should be less than the battery voltage but not zero, or pulsing in sync with the engine (if you know the spark dwell angle, you can calculate the voltage by multiplying it by the number of cylinders, dividing by 360 degrees, then multiplying by the battery voltage). If you don’t get any indication that the coil is being switched to ground to generate the spark, your distributor contact (for mechanical ignition switches) , magneto or electronic ignition module could be the problem. Before changing whatever one of these you have, double-check the wiring to the coil – a misplaced, broken or loose wire will have the same effect.
