The degree of vacuum at the throat main nozzle and the idle nozzle disappears, the fuel is no longer ejected, the fuel is replenished until the pressure in the oil chamber is equal to the atmospheric pressure, the diaphragm is in an equilibrium position, and the pressure-regulating lever adjusts under the action of the pressure-regulating spring force. The pressure valve shuts off and starts to enrich. When starting, it is required to supply a relatively rich mixture. Therefore, before starting, it is necessary to press the starting thickening rod to open the pressure regulating valve. The fuel flows into the fuel chamber under gravity and overflows from the nozzle. Increase the effect. When starting, you can also close the throttle to increase the degree of each nozzle to enhance the pumping effect of the fuel, to provide excess fuel, thereby playing a strong role. Immediately after the start, the damper should be opened. Otherwise, the engine is shut off due to the mixture being too rich, and the adjustment of the carburetor to adjust the carburetor is appropriate, which will directly affect the engine's starting idling acceleration power consumption and so on. The factory's pneumatic fire extinguishing machine has been adjusted. After the carburetor cleaning and maintenance, Sichuan vacuum pump should adjust the oil needle to its original position. Since the engine is running at idle speed, the mixture gas concentration is controlled by the idle oil needle, the screw is turned into a lean speed, and the screw is turned into a thicker speed. It is adjusted until the engine can run stably at idle, and it can also get slick during acceleration. The transition to increase the throttle, the engine does not turn off so far. Nickel-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent corrosion resistance, high temperature strength, and good weldability. These alloys are typically composed of nickel as the base metal, with various alloying elements added to enhance specific properties.

3. Monel 400: This alloy powder is known for its excellent resistance to corrosion, particularly in marine environments. It is commonly used in applications involving seawater, chemical processing, and oil refining.
4. Inconel 718: This alloy powder is known for its high strength, excellent resistance to corrosion, and good weldability. It is commonly used in applications involving aerospace, oil and gas, and nuclear industries.
5. Inconel 601: This alloy powder is known for its excellent resistance to high-temperature oxidation and corrosion. It is commonly used in applications involving heat treatment equipment, chemical processing, and power generation.
These nickel-based alloy powders can be used in PTAW processes to create high-quality welds with excellent mechanical properties and resistance to corrosion and high temperatures.
The concentration of the mixture is controlled by the idle oil needle when the engine is running at idle speed
