Fuel System Problems A clogged fuel filter or faulty fuel pump can cause issues with fuel delivery. This results in a fuel mixture that is too lean for the engine and results in backfires through the carburetor.
What can cause a backfire through the intake system?
Although there are many problems that can cause the intake system to backfire, the overall effect is the same. Since the intake valve needs to provide the engine with a proper balance of fuel and air, a backfire occurs when that balance fails.
Why does my car engine not want to start?
If the engine still doesn’t seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator.
What to do when your car wont start after a backfire?
You could try pinching the fuel line gently enough with a clamp to shut off the fuel 30 seconds before you shut the engine off. That would tell you when you return to your first start of the day that you may have had the carb run over slightly if the backfire is gone. I was going to suggest that the carb may be flooding as well.
What causes a car engine to backfire when the injector wears out?
Usually, when an injector clogs or wears out, causing the air-fuel mixture to lean, the combustion process weakens and fails to properly burn the fuel. Too much unburned fuel then enters the exhaust system where the fuel ignites with a loud bang.

Why does my car backfire when I restart the engine?
Remember that backfiring is caused by skewed ratios in the air-fuel mixture. For the next ignition, maintain a light pressure on the gas pedal while restarting the engine. Once the engine is up and running, you need to floor the gas pedal.

This step will help you narrow down the possible causes of why fuel is not reaching the cylinder. With the fuel valve open, disconnect the fuel line from the fuel inlet of the carburetor. Turn over the engine to see if gas is coming through the fuel line.
