The smell that you are getting is a result of your fuel jets are blocked with a foreign body, check your fuel jets. Depending on the age of your vehicle they will need to be replaced.
correct answer
the smell is caused by unburnt fuel leaving the engine as you are cranking it nuthing to do with blocked fuel jets. if fuel jets are blocked, you wont get fuel at all. u might check condition of battery to ensure engine is cranking at correct speed . if battery is low, engine takes more cranking to start hence the fuel being lost .
i think u need to change the O2 sensor in this case.check the air filter if it is bad.
Leak in exhaust system?
Head gasket

because of the exhaust
The car exhaust smells like the rotten eggs as a result of the hydrogen sulphide. This usually happens, when the engine is not serviced for a long time.

It smells.
Likely an exhaust leak
Most likely your exhaust is rattling and the smell is because your catalytic converter is bad
Sounds like you have a coolant leak.
When you start the car, the hot exhaust condenses on the interior of the cold exhaust system. This is normal for a few minutes until the exhaust system warms up. If the water smells and taste sweet, and you are continually adding coolant, you may have a blown head gasket. If this is the case, do not continue to drive the vehicle as serious damage will be done to the engine.
