Check the screws that adjust the carb and idle. If they get too loose, they rattle out of place, or simply get gummed up. Check the gas line for a rupture. Be sure your gas mix isn’t too rich.
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 plug is clean or you`ve replaced it and the mower still won`t start, the issue could be a lack of fuel. Either the carburetor is dirty and not able to mist the fuel to be mixed with incoming air, or no gas is getting to it to begin with.
A Poulan Pro chain saw engine needs air as well as fuel in order to produce the proper combustion for firing. An air filter that is dirty has clogged passages which restrict the amount of air that can enter the carburetor. As a result, the fuel-and-air mixture may be too rich, resulting in starting difficulties.
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: The spark plug gap on all products is . 025-inch.
When the plug is not working optimally, it is frequently because the gap between the spark plug electrodes is either too close or too far apart. In fact, many mechanics will take out spark plugs, examine them, and adjust the gap to factory settings as opposed to replacing the spark plug entirely.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
If your lawnmower is starting and then stalling, the most likely issue is the carburetor. The most common issue is that the carburetor is dirty. Here`s what you need to know about how a dirty carburetor can cause a lawnmower to start, then stall out and die.
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.
The most common reasons a Chevrolet Spark won`t start are a dead battery, an alternator problem, or failed starter.
Certainly. I`ve seen bad brake shoes out of the box, bad body control computers, bad ignition coils, and yes bad spark plugs. Anything can be bad out of the box.
To answer your question in one word – YES, the wrong spark plugs or incorrect spark plug gap can and often will cause a vehicle`s engine to misfire or run incredibly inefficient.
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.
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.

Remove the spark plug and inspect if it is dirty, cracked, eroded, or damaged. There may also be a heavy carbon buildup or a burned-up electrode. If the spark plug has one or more of these issues, replace it with a new one.
You can find Poulan Pro products both in-store and online at home improvement retailers, hardware stores, and mass merchants all over North America. We are here to help you tackle… ANY YARD.
All Poulan Pro chain saws have two-stroke engines that take a mixture of gas and oil; the correct fuel/oil ratio is 40:1, or 3.2 ounces of oil per gallon of gasoline.
Poulan is a brand name of the Swedish manufacturer Husqvarna AB.
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.
Simply, the engine will not start if the spark plugs can`t produce enough spark to start the combustion process. Some of the other causes for difficulty starting include issues with the ignition system, a battery needs replacing, or worn-out spark plug wires.
A good spark will be blue-white and will be plainly visible in daylight. If a good spark is present, the problem is probably not in the ignition system. Check the fuel system and/or stark timing. Weak sparks are orange or red and may be hard to see in daylight.
Contaminated or fouled spark plugs are unable to ignite the fuel, which could be causing your no-start condition. Like the spark plugs, the ignition wires also need to be periodically replaced. Every engine requires a specific amount of compression to crank.
Can a bad spark plug cause a car not to start? Yes. The spark plug ignites the fuel/air mixture inside the cylinder. If the fuel doesn`t burn, the engine doesn`t make power.
Check the following: Clogged muffler, clogged exhaust port, fuel restrictions, low compression, poor ignition spark, too much oil in gas or improper air/fuel mixture in carburetor. . Clean carburetor jets and air filter. Check clutch gear wheel for worn or greasy clutch pads.
