My soap in my briggs and stratton pressure washer won't come out

SOURCE: does briggs and stratton make the engine for

If it is a DPH it has a Honda engine. If it is a DPD it has a Dewalt engine that is made by either Honda or is a Chinese copy of the Honda engine. I looked at a photo of the engine and it looks like a Honda engine not a Briggs engine. Look on the engine data plate and if it says Made In China it is a chinese copy. If it say's Made In Japan it is a Honda. Some Briggs engines are made in China also so it is hard to tell except by the looks of the engine. The Chinese copy of the Honda engine looks exactly like a Honda.
