A car's throttle does not control how much gas goes into the engine, it controls how much air enters it by actuating a butterfly valve in the carburetor. You can see this by taking the air cleaner off and manually actuating the throttle cable. The increased air flow then has the effect of causing more gas to be sucked into the engine, but the throttle does not directly control gas flow. | |
