Which risk increases when fuel flashback occurs back through a carburetor?

💡 Explanation

Fuel flashback creates combustible mixture in the intake; auto-ignition causes an explosion, because unburnt volatiles are in the manifold. Therefore auto-ignition is primary, rather than catalytic failure, which requires prolonged elevated temperatures.
