Two ends of the tachometer: connect one end of the code meter gear and one end of the code meter. The end of the gear connected to the code meter will lower the gear of the code meter, that is, the front wheel drum brake. Plug the square line in the code meter line. One end of the code meter is inserted into the back of the pointer shaft of the code meter, and then there is a metal cap with thread for fixing, which is screwed tightly.

There are three wires on it. According to the normal table, the three wires are black, green and yellow. The black wire is connected to the key opening wire of the key door. The green wire is connected to the ground wire, that is, the ground wire. The yellow wire is connected to the flameout wire of the igniter. It is usually a black and white wire. How to connect the flameout wire depends on what igniter you are. You can also connect it to the flameout wire of the key door.

The tachometer indicates the speed of the engine. There is × 1000 means that the number of revolutions the pointer points to at that time is thousands of revolutions per minute. Experienced people can better master the working state of the engine and better control the number of revolutions of the engine. Generally, the speed of small displacement engines is controlled below the red line of 10000 rpm. The driver can know the engine operation at any time, and coordinate with the transmission gear and throttle position to keep it in the best working condition, which is beneficial to reducing fuel consumption and extending the engine life.

The higher the engine speed is, the more fuel it uses, but the lower the engine speed is, the more fuel it also uses. About 5000 -- 6000 rpm is the most fuel efficient, and the sound is good. It's OK to start in second gear. As long as you have good skills, it's OK to start in third gear. If you are a novice, you'd better start in first gear, which is good for both the car and people. There is no rule on how many yards to shift. You can change as many yards as you want. The engine speed should be above 4000, otherwise it is easy to shift.
