Close venting screw (1) on pump
ball (2) and pump air into the car-

The carburetor is airtight if this
value remains constant. If it
drops, however, this may be due
to two main reasons:
1. Inlet needle does not seal pro-

damaged or inlet control lever
jammed).
2. Metering diaphragm damaged.
The carburetor must be repaired in
both cases; refer to the "Carbure-
tor" manual.
