The utility model discloses an ignition system suitable for a small engine, and the ignition system comprises a charging module which is used for carrying out the sampling and energy storage of a voltage waveform induced by a charging coil, and supplying power to a booster coil group; the ignition system suitable for the small engine further comprises an MCU, a resistor R9, a resistor R11, a capacitor C8 and a diode D7. The voltage of the first trigger signal is reduced through a resistor R9 and a resistor R11, then the first trigger signal is filtered through a capacitor C8, the voltage is stabilized to a range which can be borne by the MCU through a voltage-regulator tube D7, then the MCU collects the first trigger signal, and the MCU outputs a pulse signal at least according to the first trigger signal; and the MCU is in signal connection with a display, so that the display calculates or/and outputs the rotating speed according to the period of the pulse signal. The ignition system has the beneficial effec
