King Suzuki is slow at 3000.

At the starting speed of 3000, the speed is very slow. In fact, this situation is a typical engine and carbon increase.

For example, if the throttle valve is too dirty, it will reduce the atomization effect of the nozzle. It is also possible that the engine cylinder pressure is too low, which will lead to the power drop, so it can only be started normally with a large throttle valve. It is also possible that the ignition ability of the spark plug is reduced.

Suzuki acceleration is very common. But it won't be as bad as you say. Please check how your car is idling, whether the engine speed is stable and whether you have eaten. If yes, check the carburetor, clean and adjust it. Of course, professional operation is needed. If the speed is stable, check whether the friction plate slips slightly, which will affect the acceleration.
