Why would a 2 stroke pour raw fuel out exhaust?

1. Incorrect fuel mixture ratio: If the fuel-to-oil ratio in the fuel mixture is too rich (too much fuel), the engine will struggle to burn it all, resulting in unburned fuel being expelled through the exhaust.

2. Faulty carburetor or fuel injection system: A faulty carburetor or fuel injection system can cause excessive fuel to be delivered into the engine, resulting in unburned fuel being expelled through the exhaust.

3. Worn or damaged piston rings: Worn or damaged piston rings can allow excess fuel to seep into the combustion chamber, which can lead to unburned fuel being expelled through the exhaust.

4. Faulty crankcase seal: A faulty crankcase seal can allow fuel to leak into the crankcase, which can then seep into the combustion chamber and be expelled through the exhaust.
