ver worked on a mower before, I don’t know, nor do I know how to clean it. I have been trying to find an online repair manual, which SHould have come with mower, to see what to do, but am having no luck. I also wanted to know if the muffler comes apart at that seam, or just unscrews?? My model # is 11A-074E065. Under that it had these smaller numbers: 183617
Please help broke, single mom trying to mow the darn yard!!
Thx,

Experienced gardeners share their insights in answering this question :
Have you been using old gas or did you let it set the winter with old gas in it. Today’s ethanol additive in our gas causes the fuel to go bad after about a month. Bad gas may not let it start or make it hard to start. Letting it set over the winter can cause corrosion in the carburetor or deterioration of carburetor components.To check if the spark plug is working, remove the sparkplug and ground it to the engine while turning over the engine, if you see a good blue spark your problem is elsewhere, like the carburetor (single most common cause of engine start problems). What is the make of your mower? Is it a push or rider? What is the make and horsepower of the engine? What is the model number of the engine?I hope I am able to help.

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 :

Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
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.
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. If your ignition start or push button start needs replacing, consult a Briggs & Stratton dealer near you.
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.
Spark plugs ignite the air-fuel mixture that`s injected into the cylinders. For spark plugs that don`t spark dependably, it will cause an engine misfire that robs you of performance. Cracked porcelain insulators and worn electrodes are the common issue. If more than one spark plug fails, your engine may not start.
If it won`t start or fire with spray fuel, you probably have an ignition system problem, most likely a bad ignition coil. However, if it starts and dies, that proves the ignition is working and the problem is fuel starvation. Check the fuel filter first by disconnecting the fuel line from the filter to the carb.
Causes include the wrong plug (too “cold”), excessive idling or light loads, carburetor choke out of adjustment, defective spark plug wire, carburetor adjusted too rich or low engine compression. If a spark plug from a 4-stroke engine has a wet, black oily film over the entire end of the plug, it may be wet fouled.
If you haven`t turned on your engine recently, your mower won`t start and/or you have to tug repeatedly on the rewind to start the engine, a damaged spark plug may be the culprit. These problems may also cause excessive fuel consumption, deposits on the cylinder head and oil dilution.
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.
If the riding mower makes a heavy clicking or a rapid clattering sound when the key is turned to the start position, there is a problem with the battery or a part of the starting circuit. The clicking noise comes from a part called the starter solenoid.
Bad Sensors

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.

This usually means the battery is bad and incapable of handling a huge request for power to crank the engine over. Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then as soon as you let go of the key, the headlights QUICKLY bounce back to white and bright.
1 Start motor engages but the engine doesn`t turn

The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.

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.

Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
Yes, you can spray carb cleaner (or carburetor cleaner) inside the spark plug hole. This`ll help dissolve the hardened debris and loose materials in the spark plug well. After that, you can remove the filth with a compressed air can.
Before reinserting the spark plug, spray a good lubricant such as WD-40 into the cylinder and pull the starter rope several times to distribute the oil throughout the cylinder.
Start with the fouled spark plug possibility. Try clearing the plugs by running your engine up to 2000 RPM on both mags leaning to about 50 RPM lean of peak (continue to lean until you maximize RPM, then lean further until you lose about 50 RPM).
A: This spark plug should have a gap set to 0.02 inches.
The relationship between crank and cam timing events can also cause no spark, especially on Chrysler products. On these vehicles, the PCM won`t trigger the ignition coil if the cam and crank are out-of-sync.
However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn`t run at all.
Symptoms of misfiring spark plugs include rough idling, uneven power when accelerating, and an increase in exhaust emissions.
Spark plugs aren`t universal; you have to make sure that you buy one that fits your mower. You can consult your owners` manual to determine the types your lawn mower can use or take a look at the plug`s ceramic insulator, which usually has the number printed on it.

I can’t get my mower to crank. To me, the spark plug wire looks a little corroded, but since my Owner’s Manual has VERY little info and I’ve never worked on a mower before, I don’t know, nor do I know how to clean it. I have been trying to find an online repair manual, which SHould have come with mower, to see what to do, but am having no luck. I also wanted to know if the muffler comes apart at that seam, or just unscrews?? My model # is 11A-074E065. Under that it had these smaller numbers: 183617
