Abstract
A booster venturi (21) is removably mounted to the barrel (11) of a carburetor (10), with the venturi ring (26) concentrically located in the barrel. The support conduit (28) extending from the venturi ring (26) terminates in a threaded end that protrudes through a fuel port (50) in the sidewall of the carburetor. A connector nut (30) is threaded onto the threaded end of the support conduit (28), to seat the protrusion (40) about the support conduit (28) in the correspondingly shaped and sized recess (42) in the sidewall (46) of the carburetor. The connector tool (80) has a probe (84) that fits the internal passage (32) of the support conduit, and tool protrusions (86) that engage the tool bores (72) of the connector nut (30) so that the nut can be mounted first on the tool (80) and then the nut can be properly positioned in the fuel port (50) and rotated about the threaded end of the support conduit (28) to precisely and rigidly mount the venturi ring (26) concentrically in the barrel of the carburetor.
