Question about Karcher 2500 PSI Pressure Washer

1 Answer

Choke needs to be on all the time

I bought a new G 2600PH Karcher 2 weeks ago, and it runs fine and works fine. But I can never push the choke back in or it immediately dies (Honda engine). Karcher say I need to bring it back and replace it. This would be a real hassle for me. Any ideas?
If I need to run it with choke always out, does this damage it in any way - does it consume more fuel, create more CO2, shorten the engine life in any way?

    I'm having the same problem with my 2500vh? I have never been able to put my choke all the way in, but it seems to be worse this year finding the sweet spot for the choke. Any resolution from anyone??

    I have same problem. Removed and cleaned carb but still same results. I noticed that if I spray carb cleaner while it is running near the throttle valve shaft at the top of the carb, it seems to run good for about 5 seconds and then gets rough again.

Your problem is in the carb. for some reason there is a stoppage or clogg in the venture opening that feeds the main passage to the manifold. that is the little pipe connecting the carb to the engine.the choke being on causes the engine vaccum to **** gas from other resourses in the carb to run. also check to see if throttle butter fly is moving freely.there may be a defect with the carb and they will have to replace. running the engine with choke on causes it to run rich and will foul the plug eventually . also not good on gas . will use way more than it should. also co2 level way up.

Start OK but if after warm up I push the choke to run, the engine stops, I used 4 time before and idled OK

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.

Sounds like debris in the carburettor. The carbs on these are relatively simple things which come apart easily. Check for debris or water in the float-bowl, and ensure both your idle and main jets are clear and you can see daylight through them.

Im trying to start but it wont start....whats does it mean to flood it out! i borrowed from friend and he says he used it 2 days ago and it started just fine.

flood it out means that there is too much unburnt gas in the cylinder. the spark plug is probably wet with gas. simple fix though. just pull the spark plug out, pull the cord on the engine a few times and let everything set untill the gas evaporates. then put the plug back in and try to start it. easy with the choke or it will happen again.

Pressure washer with 5hp Honda will ONLY run with choke on

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

% 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.

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 :)

Pressure washer wont run unless choke is on

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....
