Sounds like the carb is badly clogged internally. If you can remove it yourself, you can soak it overnight in a can of carb cleaner. But keep in mind some of the internal passageways in the carb are as fine a human hair and soaking may not work, it which case go to plan B, new carb. Last resort you could try to find cleaners small enough to get in the passageways of the carb, I've heard of people using wire brush bristles for example. Today's gas is terrible, it does not take long to gum up the carb, if it sits for any time.

When I move the choke to run the motor dies....even after 30 minutes of running.


No, but it sounds if the carb needs to be cleaned! Fresh fuel helps too. Check the spark plug and check the breather filter. Also you can crank the engine with the breather filter off and try to move the choke to run then. If it runs with the filter off then there is your problem! 1 question, has anyone try to work on it or adjust the carb in any way?

Why does Honda GX340 die immediately despite fresh gas, cleaned carb, and new plug?


Perhaps you haven't adjusted the carburetor correctly.The fuel supply orifice could be still plugged . Recheck the carb.

I PRESSURS WASH FOR A FEW MINUTES THEN ENGINE STARTS TO SPUTTER AND LOOSE PRESSURE. IF I CONTINUE IT WILL JUST QUIT.


Hi and welcome to FixYa I am Kelly.
Things that cause this symptom are:
1. Debris in the carb float bowl
- Remove the carb float bow nut and clean out the bowl, the bowl but and up inside the treaded area of the bowl nut is the main fuel jet. Make sure to clean that also. You can try carb cleaner but sometimes the jet has to be removed to clear it.
2. Fuel selector sediment bowl is full of debris.
- Unscrew the sediment bulb under the fuel selector and dump out the sediment
3. Dirty fuel filter (if used)
- Check fuel flow at the carb main fuel line connection. If should fill a spray paint can lid in about 8 seconds. Anything less and you need to look at the fuel filter or fuel tank exit port as a source of restrictions.
Once you have good flow here you need to check fuel flow at the float needle.
4. Debris in the fuel float needle seat. Another flow check with a spray paint can lid catch basin.
- The spray paint can lid should fill up in around 10 seconds when you turn on the fuel selector.
Poor fuel flow here and you have to remove the float, hinge pin and float needle. Then spray into the float needle hole with carb cleaner with the MAIN FUEL SUPPLY HOSE DISCONNECTED. Also spray into the main fuel line connection so that any debris is removed.

Performing the above steps should improve your engine performance dramatically. If you still have the problem after performing the above steps respond with your ENGINE MODEL NUMBER and there is more that can be done.

Thanks for choosing FixYa, Kelly

I cannot get my honda 2500psi pressure washer to start at all i have changed spark plug and do have spark it has good gas in it and plenty of oil but will not start?


Three things needed for engine to run. Fresh fuel, good spark and good compression. I am assuming that water supply is disconnected for now and that you feel good resistance when you pull the rope indicating that there is compession. For now remove/unplug the low oil alert wire (if your model has one). Use carburator cleaner as fuel for now by spraying fuel directly into carb with air filter removed and choke off (do not flood just spray a little then little more if needed, the engine will only begin to run then stop unless you contine to spray fuel). If the engine does not respond most likely timing belt or plastic cam is cause. GCV series honda engines use timing belt with plastic cam gear. Gx series use metal gear. If the engine responds clean carb. Good luck

I have an Excell model XR2600 pressure washer that will not start. I have had it stored for 3 years. I drained the gas tank and carb and put in fresh gas. Is there a fuel shutoff on this model ? It has a...


If it's been sitting for 3 years most likely the carb is gummed up. If it's getting spark, you could try a small shot of starting fluid into the carb. If it runs on this you know it's a fuel problem. Best bet would get all the MOTOR data, and buy a carb kit from you local lawn and garden equipment parts supplier. . Remove carburator and clean and install kit. Use sta-bil when you put it away next time, but even that only works about a year or so.

My gas pressure washer fell in the pool while running. Is it a goner?


Maybe, there is a slim chance it died before sucking water into the cylinder and cracking the head. To try and fix it drain out all motor oil buy a can of carburetor cleaner and spray the engine out remove the oil plug and the spark plug and spray some wd 40 into the spark plug hole, replace the air filter dry the spark plug and clean the fuel tank and replace the fuel filter inside the fuel tank replace oil with fresh oil and then give it a try. You’re out $20.00 but if it runs you are one lucky person.

It won't stay running


You need to either clean the carb really good (take it apart) or rebuild it or both. Sounds like your needle is gummed up and not letting fuel through.

% hp Honda Motor runs on choke


Dear LC39B,
Is it possible you are blaming the wrong part of the machine? Did you try the Honda Motor on its own? I am asking , because if the pump of the washer has some fault or a bit jammed, this will demand a lot of power from the Honda. You can try the Honda with no water connection and no gun.
Regarding the Honda motor, you should check the electrical system also. I am saying this because you did not mention it, in your service procedure.
Regards,
MG.
