K-151 series carburetor for "Gazelle" is produced with a wide cap. The valves in the modification are able to withstand high pressure. Among the features, it is important to mention the high-quality pump that is installed in the device. Also, the model is actively praised for the wide camera. Of particular interest to people is the adjustment of the K-151 carburetor. You need to watch a video on this topic before parsing the device. During adjustment, it is important to strictly follow the instructions. To understand this issue in detail, we recommend that you first of all study the device of the K-151 carburetor.

General arrangement of the carburetor

Consider the Gazelle K-151 carburetor, which includes a diffuser and a valve system located in a wide chamber. There is a pump at the bottom of the model. Also, the K-151 carburetor device has a supercharger with a tube. The holder is fixed on the thread. On the side of the model there is a sprayer, which is connected to the nozzle.

The limiter is used with a jet. The fuel system is located at the bottom of the carburetor. Also, the K-151 carburetor circuit includes a fitting that is used with a small needle. The float mechanism is located under the chamber. Individual attention in the devicedeserves a switch. In this case, it is used with a throttle valve. The K-151 carburetor is connected through a supercharger.

Float mechanism

The float mechanism of the carburetor is made with two linings. Racks are only on one side. To clean this mechanism, you only need to remove the top cover of the modification. It should also be noted that the tube departs from the central chamber. At the bottom of the mechanism, a block is placed on the K-151 carburetor. Malfunctions rarely occur, because two overlays are used. When idling, they can wear out quite a lot. If necessary, the pad can be cut out yourself from a small piece of rubber.

Valve system

The valve system at the carburetor is responsible for fuel injection. There is a lot of pressure on the racks. The primary modification chamber is made with two supports. There is a small cover in the central part of the device. To adjust it, you have to use the key. In the side of the system, a valve is connected to the K-151 carburetor. Malfunctions of the mechanism, if necessary, can always be eliminated independently. Inserts in the model in this case are used from rubber. The jet from the valves is serge. To replace the valve yourself, you will need special equipment. Experts say that the tube needs to be cleaned periodically. For this fit a long ramrod. It is more expedient to supply water under high pressure.

Holder Adjustment

Due to the rotation of the holder, the K-151 carburetor is adjusted. Videos on the Internet about this do not always fully reveal the topic. In this modification, the holder is located on the side of the jet. To scroll it, you need a short L-shaped key. It must be rotated clockwise. During this process, a person must monitor the position of the valve. If it tilts back, then the holder needs to be turned more clockwise. In some cases, the damper may sink during adjustment. In this case, the screw must be constantly kept in the clamping state. To get the damper, you need to pry it with a sharp object from the side of the primary chamber.

Secondary modification chamber

The secondary chamber in this modification includes a powerful pump and a set of disks. The bypass valve in this case is located at the bottom of the chamber. It should also be noted that this model has a jet that interacts with the fuel system. If problems are found, it is recommended to immediately check the performance of the central fitting. If the needle does not move, then the channel is clogged.

Cleaning the camera is easiest with a nozzle. Additionally, it is blown with a jet of air under pressure. It is important not to damage the valve system. The idle speed of the K-151 carburetor is adjusted by the holder. Some people have problems with the regulator that is in the camera. In this modification, it is connected withroller.

To check the regulator, remove the cover and disconnect the top pump. Only after that goes directly to the rack. First of all, the roller is disconnected. After that, you need to inspect the base of the regulator. This carburetor is made with a small stand. If it is deformed, then the model will have to be completely replaced. Another problem may lie in a curved septum. This is due to overloaded valves. The partition can be changed separately. In this case, it is not necessary to completely remove the regulator.

Pump malfunctions

The pump of this carburetor is used with a small rack. At the top of the modification there is a handle that connects to the body. There is also a screw that secures the stand. The main failures of the model are connected with the handle. Repair of the K-151 carburetor in such a situation should begin with an inspection of the base of the pump. After that, the tube from the rack is checked. There is a small piston inside the pump. To get to it, you need to remove the bottom cover. Only after that it will be possible to twist the screw and inspect the entire interior of the modification. In this case, the adapter does not need to be touched. When replacing the handle, special attention must be paid to the jet. In some cases, it quickly sinks. The rack can be changed without a cover. During this, the most important thing is not to damage the float.

Regulator repair

If we consider the regulator of the secondary chamber, it should be noted that it is installed in the K-151 D carburetor with two racks. overlaysapply only to the top of the device. When replacing the regulator, the cover is removed first. The next step is to remove the barrier. Subsequently, it will have to be well lubricated. The flaps in this case do not need to be touched.

The baffle of this carburetor is fixed on only one clip. The latch sits quite firmly, so it needs to be pry off. Particular attention should be paid to the rack. It is more expedient not to release the holder at the same time. If the clamping screw falls out, it must be replaced immediately. Sometimes the regulator directly sinks. This happens due to the displacement of the support. In such a situation, experts recommend checking the side stand and the integrity of the camera.

How to replace the fitting in the device?

The fitting, which has a K-151 carburetor, plays the role of a holder. It is necessary for the normal operation of the valves. If the fitting goes astray, then the valves wear out quickly. This process is also accompanied by overheating of the primary chamber. Lubrication is also broken. To correct this situation, you need to be able to properly inspect the fitting. This will not take much time. First of all, a block is placed to fix the mechanism. You can also use a regular vise. After that, you need to find the clamping screws on the top cover. They are on the sides and hidden by overlays. After removing the cover, the central valve is moved to the side. This removes the pump completely.

Then you have to carefully inspect the valve. If darkening is visible on them, then the carburetor lubrication is broken. Pumpmay also suffer from this. Next comes the fitting directly. At its base there is a small head. When it deforms, the model cannot withstand the pressure that is created inside the chamber. The head of this modification is of a removable type. However, getting it separately is quite problematic. In this case, you will have to completely change the fitting.

Replacing gaskets

Gaskets at the carburetor are responsible for sealing the chambers. If you look at the bottom pads, you can see that they have a narrow base. They are held in place with screws. To change the lining on the secondary chamber, first of all, you need to fix the K-151 carburetor. After that, the jet is unscrewed. The shutters do not need to be touched. Many people make the mistake of taking all the screws at once. You have to unscrew them one by one. Thus, the lining will never bend. If we consider the upper chamber, then everything is a little different there. First of all, the carburetor is fixed for repair. The next step is to close the valve. In this case, the holder must be in a stationary state. The screws must be tightened one at a time. Additionally, a person must monitor the position of the rack. Sometimes the lining starts to slide right away.

All this leads to the fact that it can be damaged. To avoid this, you will have to use the help of a friend. One person should only supervise the holder while handling the screws. The comrade is obliged to control the overlay. If it starts to bend a lot, then it will definitely have to be changed. It is also worth noting thatthe gasket is in the primary chamber of the carburetor. It is located right behind the lid. The cap is fixed with four screws. Before screwing everything back, special attention should be paid to the lubrication of the main components. In this case, the edges of the chambers must be well cleaned.

Locking mechanism

The locking mechanism, which has a K-151 carburetor, is responsible for supplying fuel. It includes a jet, as well as a low-power pump, from which a tube extends. The primary modification chamber is at the bottom. The main problem of the device lies in the incorrect operation of the expander. It is installed on a special adapter.

You need to immediately check the adapter for blockage. To do this, you will have to disconnect the pump and inspect the base of the chamber. The expander on the carburetor is fixed with two clips that are located on both sides. The air jet in this case should not come into contact with the holder. When replacing the expander, it is recommended to carefully clean the head. At the same time, the top cover should not be rubbed heavily.

Throttle Repair

The throttle valve that the K-151 carburetor has can only move in one direction. It fails due to the large congestion of the rack. This happens due to a violation of the injection system. To correct this situation, it is first of all recommended to inspect the adapter, which is located under the pump. The easiest thing is to change the gasket. If scratches are visible on the base,so there is friction with the valve.

All this, in the end, puts a lot of stress on the fuel system and throttle. To change the valve, just detach the top cover. In this case, the adjusting screw must not be touched. In the future, it will be difficult to configure it. Particular attention when replacing the valve should be given to the front strut. The screw on it should not be clamped all the way. If you deal directly with the damper, you will have to remove the jet. In this case, the tube should not be disconnected. The damper is removed manually, and the latch is moved to the side.

How to replace the drain tube?

The drain tube on this carburetor is under the secondary chamber. She has a small length, but sometimes she twists strongly. In this case, all mechanical damage to the case and excess shaking affect. To unscrew the tube from the side of the jet, you must have a small wrench. The outlet openings of the nozzle must be immediately cleaned of dust. To do this, you can use a rag. After that, the branch pipe is disconnected from the camera side.
