OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Spark Plug with Oil (Eletrolux 380)

Guys:

My lawn mower won't work...it fire up then straight away it dies.
So i check the spark plug and there is large amount of oil on it, just wondering anyone can help me to fix it rather then taking to the shop.

Cheers
Derrick

Derrick_in_Melb,

1. Check that the air Filter is clean.

2. Check that you have the correct amount of oil in sump(only holds 600ml).

Look at this stuff first and then get back to us with a bit more of description regarding when it is running (what colour smoke)what model engine etc.

Bruce:

Both the air filter and oil is good!!!
When i start it...there is a lot of white smoke coming out and after that the engine just cut off.
Regarding to engine model i am not to sure where i can get that information....do i need to open some part in order to know what model i got???

Cheers
Derrick

Derrick,

Do you know the name of the engine i.e Briggs & Stratton or Tecumseh.

Bruce:

Electrolux 380

Derrick,

Can you post a picture of the motor on the forum as the Electrolux 380 is a model and the engine is either made by Briggs & Stratton or Techumseh.

Bruce:
It's Briggs & Stratton
Below are some pic i just took....

Derrick,


The model type & code for the motor is above the spark plug and we need that.

When you checked the oil on the dip stick does it show that the oil level is only up to the full mark on the dip stick? The reason that I am asking this is because some people over fill the oil and with the crankcase pressure it goes directly into the carby and fowls the plug.

The picture that you put up looks like the motor has not done a lot of work from what I can see it was made in 1995.

Are you getting any oil coming out of the exhaust?

Did you tip the machine over on its side to clean underneath it?

Replace the spark plug and take off the air filter and start the machine a look to see if you are getting any oil going into the carby where the air filter is.

Let me know as it looks like in the picture you have some oil on the frame at some time.

Model: 98902 Type: 038501 Code: 95100352

Just check the oil it's at the "middle" marks.

I did try to tip it to change the blaze and that is when it's start to have problems.

Bruce, so it's safe to remove the air filter and start the machine???
I did take out the spark plug and check there is oil on it, so i clean them and put it back on again and the same thing happen.

Cheers

Derrick,

Ok when you changed the blades was the engine still warm?

If so the oil would have run through the breather into the cylinder and then push out into the exhaust.

What I want you to do is clean the sponge air filter and then put it back on.

Then put some fuel into the cylinder to wash out it out. To do this you will leave the plug out and make sure that when you pull the starter rope(about six times or more) the throttle is in the stop position. This will get the excess oil out.

Then replace the plug with a new one and start the motor up and run for about 15 minutes or until it stops smoking.

Problem should be fixed.

Let us know as this will help others on the forum.

Bruce:

When i try to change the blazes the lawn mower was completely cold.

Sorry i am just making sure i am doing it right.
1. Add unleaded fuel to the lawn mower....is that what you mean when you said "Then put some fuel into the cylinder to wash out it out"???
2. Remove the Spark Plug
3. Starter Rope MUST be in "stop" position
4. Pull it for at least 6 times
5. Replace Spark Plug
6. Run the it again till there is no more smoke???

Is the above points look right to you???

Cheers
Derrick

No follow this.

Move step 2 to 1

1. Remove the Spark Plug

2. Add fuel into the cylinder through spark plug hole.

3. Throttle control should be in stop position before you pull the rope.

Then go on with step four through to six.

Bruce, with step 2 do you mean add fuel into the cylinder of the spark plug, if so how much??? till it drip out???
Below is the pic i just add with an arrow making sure i am doing it right again...

Derrick,

That is what I said into the spark plug hole and you don't need a lot just about 50ml.

hi derrick calvin here i think i know what your problem is on this briggs 4.0 hp model that gas tank needs to come off the engine in order to get this correct i see this alot when customers bring in there equipment the side bolt in the above picture should be a 3/8 " socket bolt the bolt on the side of the tank will be a 1/2 " then removing the butterfly from the governor rod and spring after that you can take the tank off you will need a briggs part # 495770 cause the next step is to remove the carburetor from the gas tank you do this with a phillips head screwdriver there are five screws holding this carburetor down to the tank remove them screws now comes the fun part pull up on the carburetor slowly and lay it to the side now take and dry up the excess gas that will be in the chamber in the tank notice the far right side chamber you will know which one cause it dont go all the way down the tank it goes so far and stops this is called the resorvoir in that tank is where fuel is stored at for the carb to prime as it is running

do you notice any dirt or trash in this chamber if there is any dirt at all it needs to be blowed out with a air nozzle be sure to have that tank empty of all fuel before doing this otherwise you may get splattered with gas and you dont want this to happen

next take the carb gasket kit 495770 and put the gasket part in first gasket part should be against the carb body itself now put the diaphagm part against the gasket part the diaphagm should be against the gasket and the tank body

after this you bolt down the carb in to the tank and re install it just like you had it when you first took it off then you prime it for about 6 times this will insure fresh fuel gets put back into that chamber we discussed earlier

this should fix the problem you have with the engine starting and then stoping as soon as it starts up the oil on the plug can be caused by improper fuel or fuel starvation will also cause a fouled plug
J19LM is the plug you need champion brand
but anyway let me and bruce know how you make out on this tutorial thanks
calvin

Bruce thanks so much after i follow your instructions it work and i have my garden done!!!!
I just found out another problems....i won't able to stop the machine unless i use a piece of wood to disconnect the Spark Plug, did pull the throttle back all (to the "STOP" position) but the machine won't stop.

Cheers

Derrick,

Undo the screw that holds the throttle cable to the engine and pull the cable back a bit till the motor stops, then tighten the screw up again.
