Pressure washer shuts down after about 15 sec. of running time. The spark plug gets carboned up?

buy a new carburator on ebay for 20.00,the diaghram and all the rubber hoses are shot,that is what ethanol does,eiher try a rebuild kit or wait 2 days for a new one

It won't shut down because the gizmo that shorts the spark plug is not working. If possible take an insulated screw driver and either pull the spark plug wire off the plug or try to touch the end of the plug and the engine at the same time. If the switch is in the gas lever there may be an adjustment on or in it that shorts the plug out.

Pressure washer takes oil in two places:
Pump oil is 20-30 weight SAE non detergent and comes half way up/ do not fill more than 1/2 way
Engine oil is 10W30 and comes half way up dip stick
IF you overfilled the oil >>> DO NOT turn power washer on it's side or upside down to drain oil >>> because engine oil will fill carburetor

When engine won't start
We pull off air filter so we have direct access to carburetor
Spray WD-40 into carburetor while starting
The engine will fire on the WD-40

You can keep spraying WD-40 into carburetor to keep engine running while moving choke to see if engine will run on it's own
Squeeze gun trigger so water comes out gun and pump pressure doesn't stop engine

If engine will not fire on WD-40
Spark is suspect
Your spark plug gets power from ignition coil
If coil is bad you get no spark > and coil needs needs replacement
Take out spark plug, clean it with WD-40 and use a bit of sandpaper in the spark gap
Put spark wire back on plug
Touch threads of spark plug to metal part of engine > pull cord and look for sparking between spark plug and engine
If you do NOT have any sparking, then coil is bad
If you HAVE spark, then your spark plug needs cleaning or replacement

If engine fires on WD-40 but will not keep running
Then either fuel or carburetor are suspect
Loosen hex nut on fuel filter located below gas tank >> if fuel flows, then re-tighten hex
Next, pull off rubber hose connected to carburetor to see if fuel flows to carburetor
If fuel is flowing to carburetor, then the carburetor is suspect.
Small engine repair shop will have carburetor cleaners

Check exhaust
There is a screen over exhaust
Make sure it is clean of carbon build-up > Use WD-40

Change air filter

Replace the gas, check the air filter is not clean.

Check your spark plugs, see if they are failing, if they are then your motor is getting to hot. meaning that you either have the fuel mixture set to high or the setting on the spark plugs are not correct causing you to burn hot.

Please rate

It can be probably the spark plug,change the spark plug.

sounds like fuel problem. Either water\trash at bottom of tank, or most likely, carb needs to be disassembled and bowl and jets sprayed out w\carb cleaner.my money is on the latter.

check oil level. it has a low level shut off switch ?? May be it

Oil level in pump and motor OK? Spark plug not fouled? Has it sat for a while - carb dirty? Running (loaded) throttle rpm not high enough?
