Diesels run a bit different than spark ignition engines. Your gas engine runs with pert near contant fuel/air ratio. To vary the power, you vary the airflow with the carburetor throttle plate. That means, for all practical purposes, the peak gas temperature in the engine is almost constant. In diesel, the fuel/air ratio is variable and the more fuel you put in the hotter the peak temperature. The diesel engine has no throttle plate so at a given rpm, the airflow being sucked in is conatant. Adding mre fuel increases the power at a constant rpm. It also increases the combustion pressure and the piston crown temperature, which adds to the internal structural loads and the cooling requirements, respectively. So yeah, you can overfuel a diesel engine to get more power but if the components are not designed for it, the durability of the engine will suffer.
