20 Most Recent Karcher 2500 PSI Pressure Washer Questions & Answers

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....

Just bought one of these for $100 on craigslist with out knowing anything. After 5 mins of use the pressure was varying all over the place and the pump binding up to the point white clouds of smoke where coming from exhaust. After tons of online research w/o success I just figured I had nothing to loose so I tried my own fix and now I have over 3 hours of solid use stripping old paint from house with out a single issue. All I did was 1 ) Remove the black screw off tube pointing up on water pump. ( was caked with gritty oil deposits) cleaned out old oil. 2) Used red hot nail to put single hole threw center of top 3) Re- Install tube 4) Took a Manual 8" Multi Sports Ball Air Pump with Inflation Needle and removed the top to poor in Oil then re-sealed ( I used old Mobile 1 0/20 synthetic from my last oil change ) 5) Injected oil with pump threw center hole, you will feel the pressure build up and then feel and hear the oil rushing threw to the pump 6) I placed a Plastic Round Cap Roofing Nail threw the hole to help keep out water. Simple fix but it saved my $100 investment as the pump now is running strong with great pressure!

you need to use i believe the black tip where there in least pressure it does not work with pressure

Carburetor float is stuck and flooding the engine. Replace the carb. STEP BY STEP HONDA GCV 160 CARBURETOR CLEANING THE CORRECT WAY

i did and thanks - just picked up one that does the same thing and i plan to take your advise

Thank you Jerr

did you forget to shut off the fuel before moving your pressure washer? It sounds like the engine is flooded. Honda GX engines are famous for flooding with the fuel valve left on when moving. Or did you store it in a tilted position? Take the spark plug back out and pull the pull rope a few times...you should see the gas that flooded ejected from the plug hole. Once you feel you got all the gas out, replace the plug. You may want to check your oil and make sure it isn't full of gas now also. If it is good, or you have changed your oil then start it up....It should not have the resistance anymore and should start just fine. Good luck

leaving fuel in a bowl will cause corrosion in the jets and jam the needle and seat operation take the carby off the machine and go to a shop that can overhaul the unit

I had the same problem with my Karcher. The recall was lifted Aug. 0f 2007. Tried numerous people at Karcher....head of Customer Service, vice president, etc. No one returns telephone calls not even cutomer service....poor, very poor customer service. Thinking about calling Germany.

Yes, fill'er up.

Try cleaning air filter, excessive dirt build up, over oiled filter, next check wire harness kill switch etc. fuel pump,

I was able to forcefully push it back until it clicked.
