I have a yard man lawnmower briggs and stranten 6.75 hp and it won’t start.I cleaned the spark plug and still won’t start I take the plug out and it’s wet.
Experienced gardeners share their insights in answering this question :
You’re still fighting with the large amount of fuel that was in it the first time it was flooded. One way to get the rest of it out, is to take the spark plug out, and pull the starting rope hard several times to force some of the fuel out. leave the plug out for a while, and pull it again every 10 minutes or so to introduce new air and get the fuel out. If you’re not that patient, you can flash the cylinder, but be cautious with it. This is where you use a lighter to flash the cylinder. You can only do this if there’s no fuel spilled on the mower, and never put your face near the spark plug hole; it will give a loud puff sound and you may have flames jet out, but only for a fraction of a second. Then put the spark plug in, and it will probably start first pull.

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 :

A wet spark plug likely means that it hasn`t been firing due to engine flooding or a bad ignition cable. Dirt or moisture on the outside of the spark plug that provides a conductive path to ground, or an internal crack in the spark plug`s ceramic insulator that shorts the plug to ground also can be the culprit.
This can happen when the mower has been left outside during heavy rains. Moisture can prevent the spark from going off, so you may need to check the spark plug and clean it from any moisture or condensation. Clean and dry the spark plug thoroughly and use a little sandpaper to get rid of any residue if necessary.
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.
A dry plug means there may be an issue with the fuel system. A common issue is a clogged carburetor from stale gas. Using a fuel stabilizer keeps fuel fresh and the carburetor from gumming and varnishing. Third step, check the ignition system with a spark tester.
Grab your handy bottle of WD-40® Multi-Use Product and spray both your spark plugs and the area where they are housed. Allow the product to work for a few minutes, and then use your microfibre cloth the buff away the remaining dirt and product.
Wet. A wet spark plug can be the result of the engine flooding. Flooding is what happens when you try to start the engine several times without it firing up. You can clean the spark plugs or you can just wait for them to dry out.
You will need to drain the crankcase on 4-stroke engines. If water comes out with the oil, add some light oil, rock or shake the engine, then drain it again and repeat until no water comes out with the oil. Remove the spark plug and drain out any water in the cylinder.
The easiest way to tell if your engine is flooded with gas is to remove the spark plug. If it`s wet, it`s flooded and you`ll need to let the cylinder dry out before trying to restart. Compressed air can help speed up the process.
The more worn or dirty spark plugs are, the greater the pull on the rewind and more effort is required to produce an adequate spark. 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.
Can I spray starting fluid in a spark plug hole? Starting fluid is usually sprayed in the inlet of the engine (air filter end). Never in the Spark Plug hole.
Oil leaking into the spark plug wells is an indictor of a fairly serious problem that should be inspected and repaired immediately. It is almost always due to a failing gasket or O-ring but can also be the result of a failing piston or worn valve guides.
Water can result in an interruption that will make the outlet stop working; however, the wires that are connected to the outlet may carry a live electrical current. This current poses two serious risks – a fire risk and an electrocution hazard.
If you found oil has entered the spark plug tube galley then the oil may have shorted out all the coils and plug wires causing the engine no start.
