if u follow the pipe to the pump the releif valve turn clockwise to up pressure

Check the float bowl for a drain plug and unscrew it out to drain. You may have sediments clogging up the fuel passages especially in the needle & seat area
Add a tablespoon of Gumout to your gas after cleaning the float and I would change the fuel filter as well if older than a year

Put the tube into a bucket with detergent that is recommended for your machine then put the wand into low pressure mode and if it has a valve where the hose connects turn the valve to the on position and pull trigger and watch to see if soap starts being drawn out of the soap bottle if it starts pulling the soap up continue to allow it to flow till you get your part soaked with soap, then let it set for 10 minutes then hit it with high pressure hose to wash off, when it is clean then put it on low pressure and pull hose out of bucket with soap and then allow the soap to be pulled out of tube and until there is no longer any soap coming out then store the hose for use later. some machines have a control valve at the end of the wand by turning the tip or pushing tip in or pulling it out some models requires you to use quick disconnect fan tips to lower pressure to use soap.

You will need to adjust the pressure to low pressure by adjusting the lance. This way the machine will draw chemical at low pressure.

did you leave fuel in it from last year, if so remove all fuel from tank, drain carb. (remove float bowl if it doesn't have a drain bolt) put in fresh fuel, check your oil level and you should be good to go. if not, please take it to a qualified tech. for carb. cleaning.

Doc

I had the same problem and what I did fixed mine. I got it running with the starter fluid then pushed the linkage (Rod) on top of the carb and ran the engine wide open (by pushing the linkage), then released... then wide open again. I did this 4 or 5 times. Then to my suprise something clicked in the carb and it began to run normal. I have alot of experience with car engines, but not small engines therefore this had me baffled. I feel I got lucky in the repair, because something within the carb was stuck. You can not just run it wide open using the throttle...you have to push the linkage (I guess it bypasses something). Hey it worked for me. I wish you good luck and let me know if I can help in any way.

purchase a new wand from your home center.

whats it like if you remove the pump and gearbox if driven by a gearbox?

Hey mate,

You should definately be able to get one of these at your local Karcher dealer, Ive worked at a karcher dealer here in australia and you can get any part you want for them...

any where honda engines are sold---- ANYWHERE

The inlet screen orientation is of no consequence. Either way should work fine. Check two things...

1) Many of the spray nozzles have a high and low setting at the tip of the wand (where the water comes out). See if your nozzle has any "Push-Pull" movement (with the unit turned off). If so, it might be set in the "LOW" setting and needs to be changed.

2) Located on some SIDE MOUNTED pumps is a "Variable-Volume" adjustment. It may need to be turned to increase the flow and should be marked with a plus (+) and minus (-) along with direction arrow.
NOTE: If your pump is mounted on the bottom of your engine you will not have this adjustment.
Hope this helps!

sounds like your seals are going , they sell a rebuild kit for it and it is relatively easy to install

the pressure releif valve may be sticking. you will need to take it out, clean it, the put it back in. it should have a spring on it. make sure that the valve works smoothly in the bore.

The o-rings on the unloader may be worn out. Also you have to lube it with extremely good waterproof grease

The wand is plugged.
