Ans: Petrol based operating push mowers have carburetors that mix fuel and air at a specific portion. If the carb suffering from any blockage in the float chamber or floods while starting the machine, then you have to clean the carburetor. This will restore the mower’s full operating efficiency. The dirty or worn carbs may result in fuel leaking, which affects the device performance and may result in fire hazards. If you want to enjoy the strip and clean carbs, we suggest you take the mower for a service at the start of every spring. This will make it work efficiently and effectively.
