Gas Pressure Washer: 3100 psi 2.5 GPM Honda Engine with Idle

Experienced gardeners share their insights in answering this question :
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.

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 :

Heavy-duty tasks like stripping paint or removing graffiti require 2,800 psi or higher and a gpm of 3 to 4 (8,400+ ECUs). Commercial-grade pressure washers, intended for regular use and built and powered accordingly, start at 3,100 psi.
The engine of your pressure washer may rev sporadically because it is experiencing an intermittent blockage of the air that it needs to function properly. The first thing that you should do is to check the air filter for clogs caused by debris or dirt. Clean out any clogs that you find and the erratic revving may stop.
It Can Harm The Unit

A pressure washer requires water to cool and lubricate the pump, which is the part responsible for pushing water from the supply hose to the nozzle. Without water to cool and lubricate it, the pump will work harder than it should, causing it to wear down quickly.

Gasoline that sits in your pressure washer for more than six months becomes oxidized and contaminated. Degraded gasoline loses volatility and octane, causing lack of combustion, poor engine performance or a failure to start. Drain dirty or contaminated fuel, then clean and flush the fuel tank with carburetor cleaner.
Hydro locking typically happens when a wash is turned over on its side or when the carburetor float valve (aka needle) wears out and leaks which allows gas to flood the engine. Common symptoms are a smell of gas, gas leaks, high oil level, lots of smoke If the engine starts), fouled spark plug.
The easiest way to tell if your engine is flooded with gas is to remove the spark plug. If it`s wet, it`s flooded and you`ll need to let the cylinder dry out before trying to restart. Compressed air can help speed up the process.
PSI (Pounds per Square Inch) refers to the amount of cleaning pressure the machine can produce. GPM (Gallons per Minute) is the amount of water that is coming from the machine.
For most cars, a psi between 1200 and 2200 is recommended. This range provides enough cleaning power to remove dirt and grime without damaging the car`s paint or delicate surfaces.
The easy start valve is a low pressure relief valve, which directs enough water into by-pass to reach a certain pressure. Redirecting water to by-pass in low pressure, produces less load on the pump and engine.

Will only start and run in choked position, when throttle applied chokes out. If started with out choke and throttle position in low speed will start and run for 10 sec then like it runs out of gas.
ANSWER : I have your solution guaranteed, I fixed mine yesturday remove H L screw plastic caps and on high 11 threads exposed and on the low side 8 threads exposed. removing the plastic caps allows u further adjusting these wear out or move soo just take them things off and you will be rolling

Can get it to start, but runs about three seconds and stops. the choke is pushed in. But seems to want to run longer with the choke out. 4 seconds…
ANSWER : Its the old problem,,,,,,,short of fule, or no fule getting to the carb,,,,, clean out the tank filters and then clean out the carb and all the jets in it as well put in fresh fule and then it will run all day and with out the choke being on,,, thats a lot longer than 4 seconds!

ANSWER : Clean fuel system

tank
carburetor main jet, float bowl
check cable/linkage adjustments

Starts right up on choke. then run inrun position for a minute and have to go back to choke to keep it running ,then it runs fine for a couple of minutes and have to go back to choke and start all over again.
ANSWER : This happens with the cover off, so not the filter.

Have to run on half choke,just stops if i turn it off.fuel is 25 to 1. thanks alan.
ANSWER : More than likely a small passage way in the carb is clogged. You can try some carb cleaner, but you may need to disassemble the carb and clean it out. Be advised that these passageways are sometimes as fine as a human hair, and almost impossible to clear sometimes. A new carb may be required if it is worth it to you. Sorry.

Chainsaw stalls Chainsaw is 4 years old and has a history of moderate use. After I ran the saw about 1 minute on plain gas (grabbed the wrong gas can – ouch) the chainsaw sputtered and stopped.

It didn't seize, and the pull starter never became more or less difficult than normal. The engine would continue to start if I pressed the prime bulb and engaging the choke, but stall again after 10-20 seconds. The temperature that day was about 50 degrees F and I was running the saw with the “cold plug” installed (per warm weather running).

When it refused to keep running I did the following:
Flushed the fuel tank (that's when I saw the gas had no oil in it).
Ran hardware wire through all of the fuel lines.
Replaced the fuel filter and spark plug.
Cleaned the air filter with a nylon brush and compressed air.

Same behavior (start then stall in less than 20 seconds). I made at least 20+ attempts to start it.

I removed the carburetor and, though it looked perfectly clean, I took off the top and bottom covers then sprayed everything with automotive carb cleaner and blew out the passages with compressed air. The gasket and diaphragm looked new. No pinholes in the diaphragm when held against a bright light. I reinstalled the carb but got the same behavior (start then stall in less than 20 seconds). I again made at least 20+ attempts to start it.

I disassembled the short block and saw that the piston has some slight scoring on it. The ring is clean and I verified that the piston ring has .001 clearance between it and the piston ring groove all the way around with the ring held tightly in place (I was thinking that the piston might have become deformed if it did indeed get too hot when run without any oil premix).

The cylinder wall has no scoring and there isn't any signs of melted aluminum anywhere. The crank is clean as was the inside of the crank cover.

I reinstalled the crank cover using permatex non-hardening gasket goop and torqued the cover bolts to 10 inch pounds. I reassembled everything else per the exploded diagrams in Echo's “parts manual” for the CS400.

During assembly I took note that both the carb gasket and intake boot look like new.

Still the same result: press prime bulb once, engage choke, pull a few times and it starts but stalls after 10-20 seconds.

I'm stumped.

ANSWER : Not sure what to say other than its fuel starvation, if not already done replace the fuel filter in the tank, if no better i would suspect a massive air leak, so replace the crank seals, if there is no primary compression in the crankcsae fuel will not pull through the engine, good luck.

It’s brand new, when I finally get it started it will run good for about 1 min. or less, and then it dies. I pull the choke out all the way, pull it a couple of times, push it half way in, it starts but it’s like it doesn’t have the power to turn the chain, bogging out and then it dies, I will never buy another homelite product, or recommend anyone else to, this is my second one, the first one leaked gas, Home Depot really should quit selling them, there making you look bad too!!
ANSWER : Hi paulbonser… Set your point gap to .20 using a feeler gauge… You can also use a paper matchbook cover, it ia approx. .20 to set the gap on the points. Please take time tor rate me

Seems to start easily run for a few minutes and then slow and stop–bulb remains full –gas is good–have tried half choke in case too lean–did not solve–also seems possibly related to the angle I hold it at–seems to cut out quicker if blower tube angled more downward.
ANSWER : Your filter may be hanging up in the tank. you also my be losing compression
