SOURCE: spark keeps fouling but no clue why

Are you losing gear oil.
When the crankshaft seal leaks, oil from the gearbox is sucked into the crankcase, and this can foul the plug.
Also check the plug gap, most guys set the gap too small. It should be 0,7mmto 0,8mm. The plug should be a B9 EG, or equivilant.
Now, you can also change the plug cap to a type that has a built in resistor, this also helps with plug life.
Note that 2 strokes use plugs way more than 4 strokes, and you should replace the plug every 15-20 hours to keep your riding pleasant.
Good Bike you have there

SOURCE: runs rough and keeps fouling out new spark plugs

plugs could be wrong heat range they could be too cold make sure you have right heat range.if all is good.replace air filter.have injectors tested they could be leaking when you turn engine off.have charcoal canister check.check fuel pressure regulator for rupture diaphram.if all is good.scan it check egr valve.if stuck open a little it will cause rough running foul out plugs.

SOURCE: 1991 toyota 3L V6 Overfueling, raw fuel pouring out exhaust pipes

The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.

SOURCE: #1 Spark plug not burning the fuel.

did you check the gap on the spark plug? even though you buy it new sometimes the gap is off? that could make it run rough. you can also try turning the distributer to adjust the timeing but i would check the gap first? also check the gap in the cap.

Why is my atv fouling out the plug?

The big question is it being fouled with too much fuel or is it an excess of oil?

Excess fuel would initially cause dry soot to form on the insulator until the build-up becomes so severe the carbon begins to short out the spark and then plug wetting will occur. If there is a large amount of excess fuel plug wetting will be almost immediate but this will be obvious due to the inevitable bad running.
If removed it will tend to dry in the free air.

An excess of oil will start to wet the plug almost immediately but the plug won't dry in free air.

Possible causes of excess fuel: leaky carb float valve, carb fuel level too high, mixture maladjusted, blocked air filter...

Possible causes of excess oil: oil level too high, piston rings, valve guides, too much oil in 2-stroke mix, faulty crankcase breather...

A further possibility is the wrong heat grade of spark plug.

the plugs are fouling from fuel leaking past injectors and injector seals into the inlet manifold
it is nor a plug problem but injector and excess fuel problem as the fuel rail retains pressure when the ignition is off so any faults in the system will leak that pressure into the manifold

Reasons why both spark plugs keep fouling on my 1993 1340 evo harley davidson

make sure you are running the correct plug and wires for your engine and that it is properly gapped. if your piston rings are worn, excess oil burning can foul the plugs. make sure the carb is properly jetted and/or the fuel injection system is properly mapped.

Spark plugs foul immediately

Fouled plugs may be caused by oil leaking into the cylinder. Does it smoke when running (cold), are you using up the crank oil. Black smoke is excess gas comsumption, blue smoke is oil burning. If your plug is fouled with black carbon, you are most likely running to rich.

2005 Honda CR 85 R keeps fouling spark plugs

Hi, William and the usual suspects are:
1. The first thing to do if your spark plug has been fouled is to check the air filter. If it's really dirty, that makes it difficult for air to get through to the engine, causing a rich condition. Either clean it thoroughly with some Air Filter Cleaner or buy a new filter. Before you put it back in the air-box, treat with some air filter oil or spray. "WARNING" adding too much oil can also clog up the filter, resulting in another fouled plug.
2. While the gas/oil ratio doesn't equate to what the jetting is, you can still foul plugs, or worse, if the mixture is wrong. Depending on your bike, it's best to look at your owner's manual for the correct ratio. For most 2-stroke motocross bikes, a ratio is 32:1 or 40:1, the gas being 32 or 40, and oil being 1. For those that don't it, it means that for every 128 ounces (one gallon) of gas, you add 4 ounces of 2-stroke oil for a 32:1 ration, or just over 3 ounces for a 40:1 ratio.
If you have too much oil in the mixture (such as 12:1), then you will probably end up fouling the plug because it is more difficult to burn that much oil. Don't try to cut corners with the oil though, because it's very important for your dirt bike's engine. 2-stokes need the oil for lubrication on the cylinder walls, so if you don't have enough (or any for that matter) then the cylinder walls will run dry, causing it to overheat and seize the engine very quickly. So it's very important that you put in the right mixture pre-mix to your 2-stroke gas tank.
Also, 2-strokes have reeds that air and fuel go through into the cylinder, so if they are cracked or broken the bike will not run right. This could cause the plug to foul, so before you go out and buy anything expensive, make sure the reeds are still good.
3. While this usually isn't the main problem, it could be that your spark plug isn't burning hot enough. Having a hotter spark will ignite the fuel stronger, leaving less residual gas/oil in the cylinder that could cause the plug to foul. This "ISN'T" the best choice, but I'd say it's safe to go one plug hotter than stock. Keep an eye on the plug color you're looking for a light tan color anything whiter and you could burn a hole in your piston. Spark plug manufacturers aren't always the same, so make sure you find out how they rate them.
4. Almost every motocross bike comes rich from the factory (especially Honda 2-Strokes when they were being made). It's usually a pretty simple fix, but many riders are too lazy and would rather continue buying plugs instead of spending a few bucks on jets.
5. Piston rings badly worn or broken.
6. Faulty ignition coil low output.

Car seems to be flooded, smell gas and ignition just whirs when trying to start, how long do I need to wait before trying to start again?

I wouldnt start it again till you check the fuel lines for leaks(dont want to burn it up) I then suggest you look for vacuum leaks & do a compression test.pull spark plugs & look for oil fouled spark plugs &smell & observe for signs of raw gas.keep posted

Won't start

drain fuel tank. keep depressing the primer bulb until it is clear. drain tank again. remove carb cover and disconnect lines one at a time. keep depressing primer bulb to get rid of excess gas. remove spark plug an turn engine in a position that the spark plug inlet is facing the floor, pull starter rope a few times to get rid of gas in the engine chamber.
