How to adjust the carburetor mixing ratio of motorcycle tricycle 150 engine?

1. When the spark plug is white, it means that the mixture is too thin, so the oil needle should be lowered by one grid and the mixture ratio should be increased. The color of the spark plug is black, indicating that the mixture is too rich. You should adjust the needle to dilute the mixture.

2. When the fuel consumption is too high, the throttle needle should be adjusted instead of the mixing ratio screw. Raising one or two steps can effectively control fuel consumption, but there will be phenomena such as insufficient power, slow acceleration and high-speed eating, so the cars will turn dark red, so there will be sufficient power output at medium and low speeds.

Precautions for use of carburetor:

1, motorcycle carburetor is a key component in the engine, and minor changes may affect the performance of the whole vehicle. Therefore, in the process of disassembling the carburetor, appropriate tools should be used and the strength should be moderate to prevent the parts from being deformed. The removed parts should be placed neatly to prevent omission or incorrect assembly.

2, motorcycle carburetor cleaning should be carried out in a clean place. Clean the outer surface of the carburetor first, and the inside can be cleaned with special cleaning agent for carburetor or industrial gasoline. In addition to impurities, pay attention to cleaning the gasoline glue on the surface of the parts.

3. Clean the cleaned parts with compressed air, and don't wipe them with cloth or paper that will produce burrs to prevent pollution again. It is forbidden to poke the blocked small hole with hard objects such as steel wire to prevent the carburetor performance from changing due to changing the aperture. It should be cleaned with gasoline or compressed air.

4. When assembling the carburetor, the connecting screws between the float chamber and the carburetor and the engine should not be tightened once, but must be tightened several times. Generally, the tightening torque is between12n.m ~15n.m. Otherwise, the joint surface will be deformed and the carburetor will leak air or oil. The tightening torque of measuring hole parts is generally between1.5n.m ~ 3.0n.m. If the tightening torque is too high, the thread will be damaged and the parts will be deformed.
