Depends how big is ur generator. Each size will have a maximum drawing of Amps. Normally adding baking soda is to control the amount of AMPs being drawed. If ur generator max drawing of amps is 20...no matter how much u add, it will also draw 20. But if u did not add, it might just drawing 10..or even less.

As the fuel rail runs on the vacuum pressure to work correctly so if the vacuum pressure drops the fuel rail will increased the fuel to the manifold like the throttle is open so i guess i just busted the micro compressor theory.
