i dont understand the pulling the button - do you mean push the primer button - if you mean primer button it sounds like the high speed jet in the carb is dirty and needs service- you can attempt to start and once engine fires have someone continually push primer to keep running it ma clear the blockage - did You check the fuel tank for any water ?

Please note ! patients is required with this one !
Hi, remove the recoil top cover with the recoil attached. ( DO NOT TAKE OUT THE SPOOL OR YOU COULD HAVE THE SPRING GET YOU IN THE FACE)
Remove old cord.
With your new cord lace it through the recoil spool centre hole with a knott on the end.
now depending if the recoil winds in clockwise when spool is facing you wind the cord around it a few times by turning the spool clockwise,
Then put the cord in the notch at the side of the spool & wind the spool & cord anticlockwise about twice the number of turns of cord (this should tension the spring).
Take your end of the cord & lace it through the hole outside of the casing & fit you pull handle.
But hold the spool firmly untill the cord has a good knott on the end of it.
(Sometimes I see the guys here putting a loop in the cord to stop it sliping in while they tie a knott on the end of the handle.)

SOURCE: craftsman 19.5 lawn tractor w/briggs & stratton keeps flooding

This could be a number or items from no spark to a faulty carburetor, a plugged up air filter, valves out of adjustment, poor gas, faulty spark plug.

First, see if your getting spark, how about taking the wire off a plug(s) and holding it about 1/8" or so away from the plug with some masking tape while you crank the engine. You should be able to see the spark jumping the gap, it helps if it is not too light outside. If you attempt to do this with your hands, you will get a spark jolt, it hurts, so use the tape and remember, the engine could start so proceed with caution.
If you have no spark there, then you ignition or magneto is faulty. This would be unlikely in the broader scope of things. You will likely get spark. Make sure the plug is clean, take it out and inspect. If it is covered in gunk well clean it. It will smell like raw gas but you already know that. Change the plug if in doubt.

Remove and clean and replace the air filter.

If you have spark, and a clean filter it is likely a carburetor problem, Depending on the carb, it could be the choke is faulty or, as per the below.

Depending on what model you have there is a float assembly in the carburetor that stops the fuel from flooding the carb and air intake. The gas tank is higher then the carb right, so if you dont have a mechanism for stopping the fuel from leaking out the hole that goes into the engine, it will all leak out right, as into the fresh air intake because its easier than going into the engine. So, there is a miniature float assembly, sort of like your bathroom toilet float to stop the water. Well there is a small wedge type needle that seats into a hole and it is attached to a float. As the gas rises in the bowl, it pushes up the float, sealing the gas into a chamber, as you use more gas, the float lowers and more gas goes in. So ,there is dirt jammed into the float bowl sealing needle, just a little, thats all it takes. So, shut off the gas somehow, hopefully you have a valve, or squeeze the rubber line, then undo the float chamber, its one nut on the bottom. Clean carefully. The needle, little spring and float assembly are delicate. Also, the needle could be worn from engine vibration, so it may need a new needle. It would help if you described the engine and carb though.

I posted that as a solution to another problem, but yours may also be the valves need adjusting. Depending on the amount of hours, say over 200, then the valves timing will likely be off a bit. Check the clearances with a feeler gauge, it is not as difficult as it seems. Check your Owners manual for the clearance at top dead center. TDC is when you take the plug out and watch the piston arrive at the top of the cylinder through the spark plug hole when you are turning the engine over (do this by hand, battery off. Make the adjustments with the valve cover off. Follow the instructions.

Hope some of this helps.

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please do not forget to rate me, Thanks
Good Luck, I hope this helped

Why doesn't the pull cord wont move


Could be a few things but I would start by taking the spark plug out to reduce the compression. This will make it easier for the engine to turn just to make sure the piston is moving. If it is an older machine you may have rust build up all the way to a seized engine depending on maintance preformed on the mower.

Check the governer, its a lever that pulls the throttle plate from the engine side. Try manually overriding it (twist it open as the engine's running) and see if that does it.
