What we think is difficult will not be as difficult as we think. If we compare the operation of the pump carburetor and the float carburetor, the float carburetor will be much easier. Because it uses a simple principle, which is to have oil in the cup and connect the pipe up (when the air flows through quickly, it creates suction) with a jet of the required size to block it. It squeezes the oil through as desired. When it passes up, it will pass through a pipe with air holes that are sprayed up and mixed to break up the oil. When it passes through this pipe, it will meet the tapered accelerator needle, connected to the accelerator needle jacket and will allow the mixed oil and air to pass through the needle jacket to mix with the air to become complete fuel. Because when accelerating, it is allowing more air to enter. At the same time, the tapered fuel needle will also lift up at the same time. The fuel and air mixture will be able to enter more in the right proportion at every stage of the change in the amount of air passing into the combustion chamber. The disadvantage of the float carburetor system is that when it is tilted too much, the oil will overflow. Unlike a cloth carburetor, the pump can start the engine in all 360 degrees. But there must be more parts because it must have a pump to suck the oil up and compress it to the accelerator needle position and accelerator needle jacket to mix with air and enter the combustion chamber. The oil path is much smaller than the float system. Therefore, there are many problems that follow. #Rinchailai #Small engine repair #Lawn mower repair
