Re: Engine stalls out while using pressure washer nozzle
Pump issue. There is not much you can do but try spaying silicone into pump output port to loosen up the bypass and load valves. If no glory you need a new pump.

Look at the size of your spray nozzle, it may be too small causing excessive back pressure and thus excessive strain on your engine. Your nozzle should be a 3.0. If you are using the 25 degree nozzle for example, it should say 2503 on the side of the nozzle.
Remove the hose and run the machine. If the machine works and the flow of water is ok. Start checking the hose for a restriction and trigger. Make sure this is correct before you start taking the pump to bits
The unloader on your pump is bad...this is causing both problems. Find your pump model # ...probably an AR pump ...they fit the Honda GC engines well and go to this site Pressure washer parts catalog quick links Pressure Washers High Pressure... they can guide you to the correct unloader... Good luck
Could be low water pressure I have found. Also, I purchased a can of "stuff" at Lowes today which allows you to circulate a liquid substance which lubricates the pressure pump....the pump could be frozen up... I have a rotating nozzle which I bought...and it had frozen up...this stuff works
If the pressure unloader is not working correctly and/or the nozzle is partially clogged with debris, the engine will be overtasked. Try lowering the pressure by turning the pressure knob to lowest setting and test. If the engine continues to run, gradually increase the pressure. Try using the washer set to about 75% of rated capacity and use max pressure for stubborn stains. Using any machine at max will shorten the life of components. If lowering pressure does not help, then unloader is faulty or stuck. Try storing the unit with oil in the pump. Remove both hoses and infuse oil into water inlet intill all the water is displaced (let set for day or two). Good luck
My Kracher 2500 pressure washer has no pressure unless I remove the nozzle. If, I remove the nozzle and pump the trigger several times and quickly replace the nozzle it works fine until I release the trigger. Karcher (online) suggested I remove and clean the unloader which I did. It still doesn't work correctly. What another solution?
common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.
