I own a Craftsman Pressure Washer Cleaning System, Model # 580.752820. It will only run on full choke. I replaced the Fresh Start fuel cap and put in new gas. It has about 40 hours of use.When I take it off choke, it stalls.
Thanks

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking (partial or full) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.
Check for leaks

There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.

phrasal verb. choke something off. ‚Äčto prevent or limit something. High prices have choked off demand.
What happens if choke stays closed? If the choke stays closed, the engine may not receive enough air to start or run properly. This can cause the engine to run rich, meaning that there is too much fuel in the mixture, which can lead to poor performance, stalling, and/or difficulty starting.
Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine.
If your bike is only running with the choke on, it`s probably because it`s running too lean. This can be caused by a few different things: All internal combustion engines need three things to run: fuel, air, and spark. If any of these are missing or not working properly, the engine won`t run.
A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to run stall.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
Leaks are the biggest contributor to a cycling machine.

Verify if connections are tightened properly. Water leaking from a loose connection can cause the unit to cycle on and off. Verify if the pressure hose has an O-ring at the connection. If missing, this will also cause the unit to cycle on and off.

Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine.
This mainly happens when there is dirt in and around the parts of the carburetor. The areas of concern here include fuel lines, petcock, pilot jets, or fuel filters. The dirt blocks the fuel passage and it cannot reach the carburetor properly.
Even if the person does not lose consciousness, strokes and permanent brain damage, including cognitive impairment, can result from a chokehold. People with cardiovascular disease are especially susceptible to brain injury as a result of neck compression. In a paper published in 2020 in JAMA Neurology, Dr.

ANSWER : If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.

Engine will not run with out choke being puh in
ANSWER : You will need to remove the carburetor and clean. Be sure to clean the high speed jet. This jet is the bolt that holds the fuel bowl on. Remove and clean the small holes in the sides of bolt. You will need a small piece of wire or bread tie just remove the outer covering and run this through the holes. Some have a hole in the bottom and smaller hole in the threads towards the top. Clean with carburetor cleaner and blow with compressed air. Try cleaning the jet first and if this doesn’t work then clean and rebuild entire carb. Hope this helps.

Pressure washer with 5hp Honda will ONLY run with choke on
ANSWER : It sounds like it has been tipped or too much oil has been put in. This would explain the oil in the air filter. First check the oil level. Then you need to clean the oil out of the carburetor. It is dirty or plugged and that is why it only runs when choked. You can try a spray-in carb cleaner but the best thing is to remove it (if you are handy enough) and soak it in varsol for 24 hours. Good luck

Kranzle electric washer will not suck up soap
ANSWER : Hi, if it has a chemical injector on the machine then the pressure at the lance will have to be lowered for it to pull in soap. it works on a similar principle to how carburetors on cars pull in fuel, bernouli principle. high pressure at one side of an orifice going to low pressure at the other side which causes a negative pressure ( vacuum) which should pull in the soap. there should be a non return valve at the orifice (hole) which prevents the water back feeding into the soap container, it is quite common for this valve to get stuck, it is just a ball, spring and o ring , and the ball sticks to the o ring. if it is this system then take the soap pick up pipe off the injector and just push the ball off it’s seat with a bit of wire.If it is a high pressure soap system then that is different, but they usually work with an injector in my experience.try taking the high pressure hose off the front off the machine and running it, if it has an injector on it it should pull in plenty off soap.hope this helps ,andy
