Yes if air fuel mix is unbalanced car will not start and you need to get your carburetor checked
A rich condition.
Yes, most definitely but will run rich as engine temperature plays a big roll in fuel / air mixture.
Well the preferred ratio is 14.7:1 (14.7(air):1(fuel)) so anything below this is rich.... 14.6:1 for e.g
The Dodge Stratus might not start because the battery is dead or the starter is worn or damaged. It might not start because it is out of gas or because the fuel line has water or air in it.
install a cold air intake. more air with same amount of fuel being injected will lean out the fuel/air mixture. plus you'll get more power
Yes
Simple answer: air/fuel mixture is off. Too lean means too little fuel, too rich means too much fuel. Can be adjusted via air/fuel screw on a carb or via a remap on EFI. If you make changes to the air flow, you need to adjust the fuel as well.
Adjust the fuel/air mixture, ensure you have an unclogged air filter/air cleaner.
You are running too rich. the mixture of fuel and air has too much fuel in it,
Yes, that is true
If your 1991 Mercury Capri with a 1.6L engine smells rich, it may indicate that the engine is running too rich, meaning it's getting too much fuel relative to air. This could be due to a faulty fuel pressure regulator, a clogged air filter, or issues with the fuel injectors. Additionally, check for vacuum leaks that could affect the air-fuel mixture. Addressing these issues should help lean out the fuel mixture and reduce the rich smell.
the ratio of the amount (mass) of air to fuel. Ideal is 14.7 lbs of air to 1 lb of fuel to completely burn air the fuel. A slightly rich raitio of about 12.5:1 car produce more power at the expense of emissions.
