Check to see if the carb is clean, if so the anti diesel value could not be working. Apply 12 volts to value and see if it move's. If that works then you may what to check the fuel pump and see if it pumps. After you tried all that then you may have change the main jet size because these engines come with a small jet for the EPA.

You've hit the nail on the head.The float,needle and seat are stuck wide open.Once the carburetor bowl is full of fuel the float rises up on top which pushes the needle back into the seat shutting of the flow of fuel.As the engine consumes that fuel the float drops and opens the needle and seat filling the bowl and shutting off the fuel again.Things that cause this process to not work are:forgetting to empty or run out the fuel before storing it for the winter.Sediment buildup in the bowl.Mineral deposits in the needle and seat.
Not emptying out the carb can leave water in the bowl which freezes,crushing the float.It also promotes sediment buildup and mineral deposits.The float when crushed or cracked will not float,nor shut off fuel.Sediment takes away capacity of fuel in the bowl,very necessary for wide open throttle.Mineral deposits build up to the point that the needle and seat can't make a good seal so fuel will continue into the carburetor.
Enough information yet?
To repair,take the nut off the bottom of the carburetor bowl.There are the float and needle and seat assemblies.All three need to be replaced,$10 max.After you get the parts replace one piece at a time so you can see how they go together.Next replace the spark plug, engine oil and air cleaner.They are fuel fouled and even if you could get the engine started will only add more damage to your engine.BEFORE you put the new plug in cycle the engine by pulling the starting cord a few times to get rid of the excess fuel.When there's now more fuel in the cylinder replace the plug,filter and oil.
That's it!Take your time and you can do it just fine.Re-post if you have any more troubles.

After a long none use, I tried to wash my driveway and powered on the washer,it did, but when i tried to engage the power washer by pressing the wand lever, it did not engage. What can I do to get the power washer working?

We power washed houses for years with a 2400psi machine. The machine weighed about 90 pounds. 1 strong man could pick up the weight, but usually it took 2 men to unload it from the trailer.

A small machine can advertise 2400 psi ... but that is for 3 square inches at a time. The heavier machine shoots a 10" or wider swath of 2400psi.

We ran our machine twice a week for years. We had a honda engine. I'm sure the briggs engine is good. I wouldn't buy a used machine... unless the price was low and it started on first pull. Electric starter on your power washer might be a repair-waiting-to-happen because it is constantly exposed to water and dirt.
