What is the frustration of Suzuki Kaiyue after adjusting the valve?

There is a gap in the gas proportion of carbon deposition in Dachuan.

1, too much carbon deposit: Suzuki Hyatt taxis burn too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed from the fuel injection head will be absorbed by the carbon deposit, which will lead to too thin mixture and difficult starting.

2. Gas ratio gap: after the fuel vehicle is switched to natural gas, there is a gap in gas ratio, which will lead to poor explosive power, thus shortening the service life of the engine.
