Question: Carburetor Engine Floods When Hot?

What causes a carbureted engine to flood?

The most common cause of flooding is dirt in the needle & seat. What happens often is you clean your carburetor, then start the engine. Dirt from a dirty gas tank, or in the fuel line rushes up and into the carburetor. The fuel pump is another possibility.

How do you fix a flooded carbureted engine?

How do you start a carbureted car when hot?

From fully cold: one smooth steady pump, release pedal completely. Turn key until it starts to catch, then add a little gas if needed. From warm: just turn the key, no pumping required. If you pump it when warm you will likely flood things and have to hold the pedal down while cranking to clear it.

What causes hard starting when engine is hot?

Hard warm starts can also be traced to a leaking fuel pressure regulator (FPR) or fuel injector.

Other symptoms of a bad FPR: stalling.

How long should you warm up a carbureted engine?
