Why does my pressure washer stop running after I pull the choke?

Push choke to run???then not use on a all ready warm engine you mean you push the GAS lever ? remember a choke can work as a throttle for the engine. it can have a double function if your electric start contact is damaged you can use it to stop the running engine also.
How long you are owner of the machine , read the manual about it !
If before it worked good on this kind of proceedings as described ? then if you mean you push the gaslever to run Try it to do it again without the airfilter. I THINK YOU HAVE An AIR problem by carburator if its so clean the airfilter if its not to old. or replace
You can use for short time the choke in most cases minimize use of the choke short not more then 2 times max you pull.or electric start.
AND very important control in any case allways for THE RIGHT OIL level !!

If the engine is warm(hot) do not use the choke forget it it has no use. control your spark plug electrode i think you will find the cause.

The choke reduces the air flow into the carb. If you are having problems with the choke off, it means that not enough fuel is getting into the engine and it is running lean. When you choke it, the reduced air flow causes the mixture to be correct and it runs fine.

Check gas and oil. With water OFF, pull out choke on washer. Pull the start cord until it starts. Let run for about 20 seconds. Push in choke. Turn on water. Bleed wand line. Insert desired tip. You should be good to go now.

Hi,
Often times in warm weather you may only need to have it half choked or you may not even need any choke...experiment to see how much you need to get it to start and run...

Hello. Get a bottle of carburator cleaner which you add to the fuel. follow the directions on the bottle. This should solve your problem.

Please rate my answer as very helpful. thanks.

could be running lean try setting up fuel intake a bit richer

Some suggestions:
Is the gas old? If in doubt replace it.
Try removing the air filter and spraying carburetor cleaner into the carb Then try starting it. If it runs for just a minute, then stops, the carburetor needs cleaning.

mr fixit, I have pressure but it just want stay running

I have a 5hp honda power washer sat for 2 years it will only run if I spray gas in the carb as soon as I stop spraying the engine stops I have took off carb and cleaned it

I have a Karcher pressure washer w/ a 5hp Honda engine. It only will run while the choke is pulled out and only runs at about half the rpm's. When the choke is pushed in.. it coughs, sputters and shuts off. Can you tell me how to fix this....
