Small funnel
Rags or paper towels
Needle nose pliers (optional)
Step to Clean Pressure Washer Carb without Removing
Disconnect the Fuel Line
Alright, the first step is going to be disconnecting that fuel line that runs from the carburetor on your pressure washer there. By detaching the fuel line from the carburetor, this is really important because it gives you direct access to the inside of the carburetor itself.
Apply the Cleaner Solution
Next, spray the carburetor cleaner solution directly into the carburetor throat using a spray bottle. You want to thoroughly saturate all the internal parts, especially the jet, intake ports, and bowl area.
Let the carburetor cleaner solution sit for 10-20 minutes to allow it to fully penetrate and dissolve any buildup.
If possible, without removing the carb, use needle nose pliers to move any components that don't move freely. This can help break up carbon buildup.
Repeat spraying the left carburetor cleaner solution directly into the carb. This will help flush out loosened debris.
Then, take your small funnel and pour whatever carb cleaner you have left directly into the main jet hole. This will let the carb cleaner flow through the whole carburetor system, helping wash away any remaining debris and deposits that you want to remove.
Drain Out the Dust
Let any excess carburetor cleaner drain out of the carburetor. The dirt or impurities mixed in the fuel you use will be dissolved by the cleaner and flowed out. Let them out and wipe them clean with a clean tower
Reassemble
Reconnect the fuel line and try starting the pressure washer. You may need to repeat the cleaning process if it's still running poorly.
Conclusion
With regular usage, carbon and varnish can build up inside a pressure washer carburetor, impacting performance. Cleaning the carburetor as described here can help dissolve and flush out that debris, restoring the carburetor function without having to remove it.
