This question is for the pump and injector knowlegable people out there. Am I correct in my understanding that the same amount of fuel is given to the engine with the throttle in the same place {N/A engine just to not make this too complicated} regardless of where the pump tming is set but the timing just changes it in relationship to the piston position to take better advantage of the same amounnt of fuel? I'm trying to better understand the pump-injector operation itself. And also that the pop pressure on the injector is the final determining factor on how much fuel the engine gets and the timing just determines when it gets this amount? I guess in an easier way to ask this is, does the engine with the throttle at lets say 25% deliver the same amount of fuel with the timiing at 1.0 m/m as it does at .95 m/m only just at a different time? Everything else being equal as far as the injectors, fuel screw ect.
