pressure washer dilemma
I have a Excell xr2600 pressure washer. Engine runs fine. Attach water, pressure hose and wand - turn on water -everything runs fine. Water comes out of pressure hose/wand ok. Add any size tip (smaller than a soap tip) to the wand and the pressure washer will run and spray full power for about 5 - 10 seconds then lug down as if gas starved and die. Re-starts and will run fine until the trigger is pulled - then 5 - 10 seconds and stop.This will happen forever. Spent many hours troubleshooting the unit including a full carb cleaning and unloader valve cleaning but haven't had any luck. Any ideas?
