Note 1: Models 3800 Export, 4600, 5000 and Pli-Solex have a high headlight that would interfere with a top mounted engine lift lever. So they have a side mounted engine lift lever. It came in early and late versions. The lever and crank must be for the same version.
Top, early lift lever 50021 and crank 50025. Bottom, late lift lever 50021 and crank with roller 50025. They both have the same Solex and Motobecane part numbers. Here we use italics to mean version 2.
Note 2: The Solex fuel pump has to move gasoline uphill to the carburetor using crankcase pressure pulses. The membrane and maybe the plastic seats and balls are needed often to replace deteriorated, worn or sticky ones.
When the top cap or post is unscrewed, the top check ball can easily fall out and get lost. Often a not working fuel pump only needs a ball, or a new membrane. Pumps sold without the top cap or post are usually missing the top ball.
The pump check balls can be tested by blowing and sucking through a piece of small rubber hose or fuel line. The lower line only blows and does not suck. The upper line only sucks and does not blow.
From La pompe à essence Solex moby92.com. There are two glass balls placed on two conical plastic surfaces (seats). Each ball and seat works like a one-way valve. The gasoline can only flow in the direction that makes the ball lift off of the seat.
There are pressure variations in the crankcase that make the pump membrane move. When the piston goes up, the membrane sucks the gasoline, the bottom ball rises, the top ball closes the valve. When the piston goes down, the membrane pushes the gasoline back, the bottom ball closes the valve, the top ball rises, the gasoline goes to the carburetor.
If a ball is stuck by dried deposits, the pump does not deliver anything. If the top ball is missing, the pump sucks at the same time from the top and the bottom, it is difficult to prime, once primed, it does not deliver much, the engine can run out of gasoline. If the conical surfaces of the seats are damaged, it is the same thing. If the copper washer is missing, the balls will have less space, the pump will flow maybe or not at all, and it will leak from the top.

Right control with wires loose, with wires taut, and end view.
The Solex reverse right brake lever also controls the throttle. Either squeeze the brake or twist the grip to close the throttle. A cam in the grip pushes that little trigger (center photo) which pulls the throttle wire. The single-ended throttle and brake wires are ordinary “universal” moped inner wires.

Yellow – main power from stator to switch paddle (power for the lighting exits the stator via the serrated stud; there is no wire connection between the serrated stud and the switch. The switch paddle must contact the serrated stud when the switch lever is turned counter-clockwise)
Red – power from headlight switch paddle, through spring and bronze strip, to headlight.
Blue – power from bronze strip to tail light wire
Green – ground (wire from headlight to fuel pump screw)
*Note: the 1966-72 S 3800 USA (and the S 3300) is similar, but instead of a ground wire, there is a ground tab mounted on the front of the fuel pump. The tip of the bulb touches the tab.
