In them there are some differences, for example, the dimensions of the nozzles, the presence of vacuum corrector. If we talk about the carb penny, it is suitable for installation only on engines used in this car model. The reason for this is that the distributor is used without a vacuum signal.

It should be noted that all the adjustments should not occur anyhow, but taking into account the percentage of CO₂ in the exhaust system. It should be noted that the carburetor VAZ-2101 contains a float system which maintains the required level of gasoline and to produce it adjustment.

Starting System and solenoid valve

Very often in the carburetor “penny” breaks system startup and idling. If the air damper is not fully closed during cold start of the engine, to start it will be very difficult. Of course, some jet the carb could simply be clogged. In this case, will full wipe. To get rid of all problems, you must thoroughly clean the air damper. And if necessary, adjust the actuator so that the gap was normal between a wall of the carburetor and the choke. In that case, if the idling engine starts to stall, the first thing to carry out diagnostics of electric valve. In particular, I was losing voltage, which is supplied from the ignition switch to the mechanism. In order to verify that enough pigtail to connect its center pin with the positive terminal of the battery. If there is no click when the power is connected, the device burned down. Hence it is necessary to change it. If there is a click, remove the solenoid valve. Then clean it and the nozzle.

Idle: setup

Similarly configured, and a new carb. Take a look at how this process occurs. To adjust idle you need to know how many rpm's should the engine develop in this mode. You need to achieve the frequency average of 850 rpm. Adjustment screw provides the quantity and quality of the mixture. First, you need to rotate the screw to achieve the rated rpm. Then, rotating the screw to achieve the maximum speed. Then rotate the screw number and reduce the speed to the original 850 rpm. Then again, start “play” with the screw. It is necessary to bring the engine up to the point where it will beginto shake. Make final adjustment by rotating the screw several turns counter-clockwise to operate the engine with maximum stability.

Throttle

Please note that you should use as clean gasoline. The carb will quickly become worthless, if the fuel has impurities. The first step is to set the position of the throttle plates in the carburetor. For carrying out adjustment requires that they are fully opened. Check position by turning the lever until it stops. In the primary chamber it is necessary that the damper has opened about 13 millimeters. The error is not more than 0.5 mm. This setting can be changed if in the desired direction to bend the bottom of the tendril. Secondary camera should open a maximum of 15 millimeters. The error is the same as for the primary camera. The size of the opening can be adjusted only by loosening the stem, which is located on the pneumatic actuator. Valve in the primary chamber is not fully opened, the tendrils on the levers when it should begin to come into contact.

Needle valve

During the rotation of the lever to the stop should close the valve of the carburetor, which regulates the amount of air. Please note that when adjustment is necessary, so that when closed the air flap primary camera was ajar no more than 0.8 mm. To adjust the accelerator pump, you need ten times to turn the lever that controlled the throttle. The gasoline that comes out of the dispenser must be collected in a beaker through which next is the measurement of the volume. The maximum value should be 8,75 cubic inches. Please note that before you scan you need to pump lever pump to all channels as full. Required during all repair work necessary to test how sealed needle valve of the carburetor. Preferably this work to carry out on a special stand. It can be used to apply to carb diesel under a certain pressure. And control, does it pass needle valve the load.

Carb repair Kit

Please note that despite the seeming uniformity of all carburetor repair kit may be very different. When you go to the store to purchase the kit, you need to pay attention not only to the car model, but also on the type of carb. In other words, if you have ‘Solex" repair kit carburettors "Ozone" simply does not fit you. Usually the kit has two gaskets that are between the parts of the carb. It also includes fuel and air jets and nozzles accelerator pump, needle valve, fuel filter, similar to a thimble, a spring. To adjust the carburettor VAZ-2101 is possible only under the condition that all its elements are suitable for use. In addition, the repair kit should be a few rubber rings. Please note that you need to buy the original kits that are produced on the territory of our country, not in China. Unfortunately, the latter may not contain some elements that must be replaced when repairing the carb. Sometimes even they have a very low quality, and there are also differences in size. So to install simply does not work.
