It is very helpful if you learn to clean the carburetor on pressure washer yourself as it will save time and cost for you. Any starting problem that occurs in small engines of lawn mowers or pressure washers can be rectified with a simple diagnosis. Ensure that the air coming into the carburetor is free of dust or dirt by examining the air filter. If the air filter is clogged you will probably note the emission of black smoke from the exhaust. Also the connections to the choke plates and carburetor’s throttle get sticky due to accumulation of dirt. Due to constant vibration of the engine and longtime use the screws on the carburetor settings are affected. Go through Mamaa.org as this is a good blog having sufficient information about pressure washers.
The dirt in the carburetor has to be removed and you can do the cleaning using carburetor cleaners. Even the passages inside the carburetor get clogged due to the debris that the engines encounter. These deposits inside the carburetor can clog the fuel path and air outlets affecting the overall performance of the engine. Fortunately, the carburetor can be removed and cleaned thoroughly outside and replaced again. The commercially available carburetor cleaners come in small spraying cans which you use periodically to clean the carburetor and improve the performance of the engine. It is not the clogged carburetor alone affects the performance of the engine but also the unused fuel, clogged sparkplug, dirty air filter and unused oil. You can avoid all these problems by doing annual checkup.
