It sounds like could be one of the problems listed below or a combination of those things.

1) The exhaust is partially blocked. Check the screen covering exhaust port for carbon and dirt build-up. High-speed exhaust air must pass freely. We finally broke the exhaust screen out with a screwdriver to get our machine going one day.

2) Gas is not flowing freely to carburetor > under gas tank, find the rubber hose connected to carburetor. Pull off rubber hose and make sure gas flows freely. You can use this hose to drain gas tank of old gas ... and then put in fresh gas.

3) Carburetor is partially gummed up and engine cuts off when gas flow slows down. Buy some gum out, and then don't store power washer with gasoline in the tank. Or put additive in gas when storing machine.

4) The choke is letting in too much gas or not enough gas. Try different adjustments. The choke-lever on our power washer got so bad that we could not set throttle at full open or the machine would die. We still use the machine at 2/3 throttle, and then start it each time using WD-40 as described below.

5) Dirty air filter that won't let engine breath enough air to keep up with combustion. Take off air filter and see if problem persists.

6) The spark coil is going bad?? Change spark plug to see if problem persists. Is spark plug wire pushed all the way onto the spark plug?

Now the nitty gritty of starting that bad boy and making you happy again!!!!

7) Take off air filter. Spray WD-40 directly into carburetor. Yes, we use WD-40 every time to start my power washer, and we use the washer twice a week. Spray in the WD-40, Pull the engine cord. The engine will fire on WD-40. Guaranteed.

Once it starts, keep spraying WD-40 directly into carburetor to keep engine going.

If engine will not fire and keep going on WD-40, then your spark is suspect.
If your engine fires and runs on WD-40 but dies without it, then your gas supply or carburetor are suspect

8) Carburetor problem >>> try Gum out >>> and then take machine to small engine repair shop

9) Spark ... take out spark plug. Put spark wire back on. Hold spark plug by spark wire. Touch metal threads of spark plug to metal opening where plug came out. Metal to metal. Pull back start cord and look for spark between the metal. If you have no spark, then spark coil is bad >>> take machine to small engine repair shop

Let us know how it comes out!!

I have a pressure washer, that i start with the choke on. as soon as i shut the choke off it stalls


First thing, if you are using last years gas stop and get some fresh gas, old gas is enemy #1 of small engines. You may need to keep the choke on longer and then only take it half way off. if it does not warm up in a minute or 2 you most probably have a fouled carb. you can try some carb cleaner that you add to the gas and see if that works.

What would cause a pressure washer to cut off after you pull the handle to get the water started


We used power washers for years

When you pull the trigger, the engine is supposed to accelerate because the back-pressure on the pump is released.

The back-pressure is why you're supposed to keep the gun trigger open when starting the engine. It sounds like you're starting the engine with no water passing through the gun.

Inspect the exhaust port >> if exhaust is clogged with carbon or dirt, then the engine will not run at high speed.

The problem may also be cause by a rusted choke lever. If you notice when a small engine accelerates, the choke lever moves up as the carburetor demands more gas.

Start the engine with water passing through the gun >>> move the choke lever a little bit at a time and see what happens. Keep water going out of the gun. When the surfaces are cool, spray WD-40 on the lever and see if you can free it up. WD-40 is extremely flammable.

If your engine will not fire at all by starting with water passing through the gun, then your gas supply might be limited or your carburetor gummed up. Pull off the rubber gas line that connects to the carburetor and see if gas flows.

Next, pull off the air filter and see if the machine runs good without air filter. You may have clogged air filter.

While the carburetor is exposed, spray WD-40 into carburetor. See if you can get engine up to full throttle while spraying WD-40 into carburetor. Keep spraying the WD-40. Keep the water flowing out of the gun.

If the engine throttles up all the way on WD-40 but won't run without it, then your carburetor is probably gummed up.

Our old power washer won't run with the choke set at full throttle. We just got into the habit of leaving the choke alone. We'd pull off the air filter and spray WD-40 into the carburetor so the engine would spark healthy without messing with the choke at all. And we kept the choke about 2/3 open all the time.

Runs on choke a little


sounds like the carburetor has gummed up a bit, and may need adjustments - or, the fuel pickup in the tank has come loose [i.e.: deteriorated fuel lines] - also, make sure your gas mix is FRESH. if your gas mix is more than 2 months old, dump it

I have an old pressure washer that uses Tecumseh H30 engine. After pumping the choke bulb on the carb, it will crank, run maybe 5 seconds and quit. Thanks


When you get it started, move the choke to the middle, then let it warm up. you might have to move the choke back and forth until it warms up, keep the throttle wide open.

I had the same problem 3 years old, maybe used 10 times - removed the air filter and the washer started fine. The air filter looked fine - I have not tried to replace it or figure out the root cause. I was just happy to get it running again :)
