Question about Briggs & Stratton 2200 PSI Gas Pressure Washer
Hi and welcome to FixYa. I am Kelly
First off make sure the oil is full in the crank case.
Remove the spark plug and check for spark with the Engine on / off switch ON.
If there is good spark then turn off the fuel and remove the float bowl by unscrewing the bowl nut.
1) Remove all of the debris from the float bowl. It must be very clean.
2) Clean the bowl nut. This to must be very clean.
3) In the threaded area that the bowl nut screws into there is a Brass fuel jet. You must make sure that the pin hole of the jet is free of obstructions. I use a round toothpick broken in half. Use it like a scraper and clear the pin hole of the orifice. DO NOT force the toothpick into the orifice hole. It will break off and clog the orifice. Spray carb cleaner downward into the brass tube in the carb throat making sure that the carb cleaner passes through the jet orifice.
4) Use a spray paint can lid to catch fuel and turn on the fuel. Fuel should flow enough to fill the spray paint can lid in 8 to 10 seconds with the float hanging down. Raise the float gently to the level position and make sure fuel flow stops. (If you are not getting fuel to the carb remove the main fuel line at the carb and check fuel flow.) I.e fuel selector lever on and off. Poor fuel flow here = clogged fuel tank outlet port of debris in the fuel shut off valve area.
5) Install spark plug fuel lines and float bowl.
6) Attempt start. It should start. If it does not start squirt a small amount of fuel into the carb and try a start. Just respond here with symptoms. I.e have fuel.. have spark / fuel in carb throat = brief start or no start.
There is more that can be done.
Thanks for choosing FixYa,

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.
