Is the throttle carbon deposit serious?

Serious carbon deposition on the throttle will cause the following symptoms: 1, too much carbon deposition on the engine, and the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposition during cold start, resulting in too lean mixture during cold start and difficult start;

2. The gasoline adsorbed on the carbon deposit after landing will be sucked into the cylinder for combustion by the vacuum suction of the engine, so that the mixture will be enriched, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter after cold start;

3. Too much carbon deposit in the valve will also cause difficulties in starting and idling jitter.
