Exhaust smells like gas?

Hello, Engines run a little rich when cold, it is the only way to get them started. This is because the amount of fuel burned in a cold engine is less than the amount of gasoline the engine con burn when hot. Since the gas is not completely burned, more has to be injected for each engine cycle to maintain the proper air/fuel ratio. When the engine heats up to operating temperature, the gas smell should subside. Engine design is a huge part of how much fuel needs to be injected to start when cold, and if your engine needs more fuel when cold than a Honda or Toyota commuter car, so be it. Now, if your exhaust smells strong like gas when it is at normal operating temperature, take it in to find out why it is calling for so much fuel.
