This does not only happen on a regular carburetor, but also in the carburetor vacuum. The problems that often arise in a vacuum carburetor is on a spring that no longer has a high flexibility, skepticism is dirty, and the membrane hardens.
The spring serves to open and close the skepticism in order to open the venturi hole with the help of air pressure. The membrane responsible for managing existing wind on the device.
Then what is the cause of the problematic component? How do I fix this?
1 spring loses its elasticity
One of the problems that often occur in the spring is the declining level of flexibility. It can happen with age as well as the use of the wrong treatment. One of the treatments, such as carburetors are often tampered with or improperly assembled. Therefore, if you feel or suspect a problem in the carburetor should bring the vehicle workshop. Another thing to keep in mind, look for the workshop which has a reputation as a specialist dealing with the carburetor.
2 dirty Skep
Other causes are many impurities in skepticism. Dirt buildup that can lead to skepticism not interested maximal alias when user drag the motor pull the gas lever. As a result, the supply of fuel to the combustion chamber is also not optimal. Conditions that cause the motor to potentially strike. Because if there is fuel in the combustion chamber has been burned, the next intake is not the case. As a result, the motor is turned on despite difficult-started several times.
When you encounter such symptoms, you should also be careful to clean dirt. Because, if not exactly the position of the spring will also be displaced. Although only slightly shifted, but its influence on the process of opening and closing of skepticism is quite large.
Therefore, do not use abrasives to clean it. Use the liquid to polish and do it carefully until the dirt washed away. This is so that skepticism may be raised again.
3 Membrane leak
The membrane is made of a rubber material in the carburetor vacuum has a very important role. Because it is very important that, almost all motor manufacturers forbid opening the device.
Another issue that often arises is, membrane leak. It can happen, because when fiddling with the device was no piece of equipment - such as screwdrivers - which touches the membrane and cause leakage. Although only small, but the leakage was causing the membrane to leak.
Air entering the vacuum chamber to move the rubber out again because there is a hole. So that the vacuum level is not perfect. As a result, skepticism carburetor can not be open to the maximum. As a result, flushing the fuel from the carburetor into the combustion chamber and also less incomplete combustion occurs. In the end, the motor power lackluster.
Other causes membrane leakage is after opening the lid membrane, the installation is wrong. That is, the position of the rubber holder attached not fit in the first place. In addition, membranes made chemicals also can not stand the kind of gasoline. The result can be hard. If it hardens, it will be difficult to raise skepticism even happen vacuum. This is the result venturi hole so do not open all.
