A fuel injection system for small engines. A controller is provided to monitor manifold absolute pressure, engine RPM and engine oxygen levels. Fuel injector pulses are synchronized to minima in the manifold absolute pressure signal. The width of the pulses is varied depending upon the manifold absolute pressure, the engine RPM, and the oxygen level. In addition, a plurality of correction factors are available to adjust the pulse width depending on engine performance.
