An internal combustion engine comprises first and second banks of fuel injection means each adapted to communicate fuel to a combustion chamber of the engine in response to rotation of an engine-driven cam shaft. Upon start-up of the engine, a handle-actuated lock-out mechanism is actuated to inactivate one of the banks of fuel injection means whereby fuel communicates only through the other one of the banks of fuel injection means. After engine warm-up, the handle of the lock out mechanism is released to permit normal engine operation whereby fuel communicates through both of the banks of fuel injection means.
