How to adjust the valve I learned to repair the car, but I can't adjust the valve, so I also attended the lecture.

Adjust the valve. Mechanically, there is a screw to adjust the gap. If it is an electronic throttle, it can't be adjusted. Generally speaking, the current cars are all electronic throttles, which can only be initialized.

Questions like that. Your systematic study. It doesn't matter. No owner. Simply think it will. When you actually operate. There will be problems. So you need to find a school to study hard.

According to the current market situation. The number of cars is increasing. And the increase is still relatively large. Think how wonderful it would be if someone had a car in the past. What about now? It is not uncommon for families to own cars. In other words, cars have gradually become people's means of transportation. Therefore, learning auto repair technology is a better technology. It is also a very popular major at present.
