For most Briggs and Stratton engines, the model, type, and code numbers are located on the air shroud.
Most carburetors have a unique identification number that can be used to confirm its make, model, and specifications. The carburetor number is typically located on a metal tag attached to the carburetor. On most aftermarket carburetors, this ID is stamped or etched directly onto the carburetor body.
Run the engine for five minutes at half throttle to bring it to its operating temperature. Then, turn the idle mixture screw slowly clockwise until the engine begins to slow. Turn the screw in the opposite direction until the engine again begins to slow. Finally, turn the screw back to the midpoint.
The idle speed screw (arrow 1) is located on the primary linkage. The idle metering adjustment screws (arrow 2) are located on the primary metering block on most Holley carburetors. A typical starting location for these idle mixture screws is between 1 and 1 ½ turns out from fully seated.
If the carburetor is new or has been rebuilt, you should set it to “factory” adjustment. You can do so by adjusting the idle mixture screws to 1.5-2 turns out, and the idle speed screw to 1-1.5 turns in. Warm the Engine Up. The engine`s running temperature directly correlates with proper air and fuel mixtures.
The fuel is drawn into the carburetor by the vacuum created on the downstroke of the piston. As air accelerates through the Venturi, it creates a low pressure area and velocity of the intake air increases. This rapid acceleration causes the air and fuel to mix and vaporize.

Similar to a walk-behind mower, the carb is located below or behind the air filter. You`ll have to remove the filter and the air filter housing to access it. Once you remove the air filter housing, you can identify the carburetor by following the fuel line from the gas tank to the carb.
Knowing the model number of your Briggs & Stratton® ride engine will make it easy to order maintenance or repair parts online or from your local dealer. The engine model number is the first 12 characters stamped into metal directly on your engine in one of two locations – on the valve cover or an aluminum tag.

Hi there, quick question, there is a black and grey wire on the 13.5hp briggs and stratton, i am unsure which is the earth and which is the power?
The grey one should get power when the key is turned on. This opens the solenoid valve on the carb and lets fuel in. The black one should get earthed when the key is turned off, this shorts out the coil and stops the spark. Aussie Steve.

An engine not starting can have many causes but it is usually due to lack of fuel being sucked into the engine or no spark.Remove spark plug. It should be damp, if it is wet, the engine has been flooded and should be left for a few minutes for the fuel to evaporate. Replace lead on the plug and hold the threaded part against the engine somehow. Make sure you don’t hold the lead in your hand!Pull start the engine and ensure there is a spark.
My pressure washer is making a sound like a car engine is in neural and the gas pedal is being presses and then released continuously
Sounds like carbeurator problem. could need cleaning or adjustment. some carbs have spring loaded adjustment screws for richening or leaning the carb look for the lower adj screw run the machine while turning the screw clock or counter clock wise and see if it smooths out , newer carbs dont have these screws and may have to be replaced or soaked in industrial carb cleaner.
