What is the effect of a blocked float chamber on engine performance?

• A. It increases fuel efficiency.
• B. It may prevent starting.
• C. It enhances air intake.
• D. It reduces smoke emissions.

Answer: (B)

A blocked float chamber disrupts the normal flow of fuel to the engine, which can lead to difficulties in starting the engine. The float chamber is an essential component in carburated engines that helps regulate the fuel level and ensure a steady supply of fuel to the engine as needed during operation. When this chamber is blocked, the fuel cannot reach the engine properly, which can create a vacuum or a lack of fuel delivery. As a result, the engine may not receive enough fuel to mix with the incoming air, leading to potential starting issues. Efficient fuel delivery is crucial for an engine’s operation, and without it, the likelihood of the engine failing to start increases significantly. In contrast, increases in fuel efficiency, enhanced air intake, and reduced smoke emissions are not direct effects associated with a blocked float chamber. The obstruction would more likely lead to higher emissions due to incomplete combustion from insufficient fuel, thus potentially increasing smoke output rather than reducing it.
