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 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.
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.
A dirty or fouled spark plug can cause your lawn mower to not start. It can also work itself loose, causing issues. If the spark plug appears to be seated correctly but the engine doesn`t start, a new one may be in order. For a few dollars, this easy fix can get your small engine working again.
Check for worn or damaged spark plug wires, worn or faulty distributor cap or rotor. Look for carbon tracks or cracks under the cap or rotor. Consult your vehicle repair manual, if necessary.
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.
The circuit breaker may have tripped
Then check around the blade and clear any debris that may be blocking it. Reattach the spark plug boot and reinsert key. Wait 30 seconds so the breaker can self-reset, then try restarting.
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.
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.
The ignition coil draws electrical power from the battery, increases its voltage, and sends the high-voltage power to each of the spark plugs. Two winding coils inside of the ignition coil converts the electricity from low to high voltage before sending it out.

No spark to spark plug wire
Have you tried cleaning the plug or a new one. Try removing the plug, reconnect it to the wire and placing the thread part of the plug against the ‘fins’. This will make the engine easier to pull and to see if spark is jumping the gap. If there’s no spark, take the plug off and hold the connector about an 1/8 ” from the fins and see if spark jumps. If not, the armature (ign. coil) may be bad. Before you change the armature though, check that the wire from the armature (terminal underneath) to kill switch is not grounding out. Information overload? lol

Yard man mower 139cc OHV spark plug
On the 139cc PowerMore, I had a similar problem with the metal jacketed Spark Plug boot. Immediately behind the spark plug boot on the left side is a larger bolt head. Grab the boot and pull away from the motor with one hand while gently applying pressure with a slot ***** diver or a handle on a pair of pliers, using the bolt head as your pivot point and get the boot off that way. Work gently, you don’t want to damage an air fin or anything else, but do know it will take a strong but short tug off of that spark plug. Also, take note that the spark plug sits in there at an angle, that way you don’t cross-thread anything.
Be firm, but patient with this and it’ll work out.
