Carburetor Fuel Shut-off Solenoid
This solenoid sits at the base of the carburetor bowl and controls fuel flow to the main jet via an electromagnetic plunger. If the internal coil fails or the plunger becomes fouled with fuel varnish, it will not retract fully when the ignition is engaged, effectively cutting off the fuel supply immediately after the engine consumes the fuel used for starting. This results in the engine firing briefly and then stalling as if it has run out of gas.

Carburetor Assembly
Small-orifice internal passages in modern carburetors are highly susceptible to gumming from degraded ethanol fuel. When the idle or transition circuits are partially blocked, the engine may have enough fuel to start under choke (high vacuum) but will lack the stoichiometric ratio necessary to maintain combustion once the choke is opened or the engine attempts to idle. Replacement is often required because the microscopic nature of these passages makes manual cleaning unreliable.

Fuel Tank Cap
The fuel cap contains an integrated vent designed to equalize pressure as fuel is drawn from the tank. If the vent membrane is obstructed, a vacuum forms within the tank that eventually overcomes the fuel pump's ability to pull fuel or gravity's ability to push it. This leads to a 'starve-out' condition shortly after the engine starts and begins consuming fuel at a higher rate.
