Priming system for a float bowl carburetor

A float bowl carburetor, comprising:

• a body with a fuel and air mixing passage formed therethrough, and a fuel bowl defining at least a portion of a fuel chamber in which a supply of fuel is maintained;
• a fuel supply pipe carried by the body in communication with the fuel and air mixing passage and through which fuel is supplied from the fuel chamber to the fuel and air mixing passage;
• a fuel passage formed at least in part in the body and having an outlet generally coaxially aligned with the fuel supply pipe;
• a priming system including a priming pump communicated with the fuel supply pipe and the fuel chamber through said fuel passage and operable to discharge fluid through said outlet and into said fuel supply pipe upon actuation of the priming pump;
• a bolt carried by the fuel bowl and having a passage formed therein with said passage defining a portion of the fuel passage;
• and
• wherein the body includes a column that extends into the fuel bowl, has a bore in which the fuel supply pipe is received, and a counterbore in which a main jet is received with a passage through the main jet aligned with the fuel supply pipe, and the bolt is received in said counterbore to facilitate coaxially aligning the outlet with the fuel supply pipe.

A float bowl carburetor, comprising:

• a body with a fuel and air mixing passage formed therethrough, and a fuel bowl having at least one wall and defining at least a portion of a fuel chamber in which a supply of fuel is maintained;
• a fuel supply pipe carried by the body in communication with the fuel and air mixing passage and through which fuel is supplied from the fuel chamber to the fuel and air mixing passage;
• a fuel passage defined at least in part by a passage formed in said wall of the fuel bowl and having an outlet generally coaxially aligned with the fuel supply pipe;
• and
• a priming system including a priming pump communicated with the fuel supply pipe and the fuel chamber through said fuel passage and operable to discharge fluid through said outlet and into said fuel supply pipe upon actuation of the priming pump.

• a fuel supply pipe carried by the body in communication with the fuel and air mixing passage and through which fuel is supplied from the fuel chamber to the fuel and air mixing passage, said fuel supply pipe includes a main jet with a passage that defines the minimum flow area through the fuel supply pipe and wherein the outlet is disposed upstream of the passage of the main jet and the flow area of the outlet is larger than the minimum flow area through the fuel supply pipe;
• a fuel passage defined at least in part by a passage defined by the body and having an outlet aligned with the fuel supply pipe;
• a priming system including a priming pump communicated with the fuel supply pipe and the fuel chamber through said fuel passage and operable to discharge fluid through said outlet and into said fuel supply pipe upon actuation of the priming pump;
• and
• a bolt carried by the fuel bowl and having a passage formed therein with said passage defining a portion of the fuel passage and wherein the passage in the bolt communicates at one end with the portion of the fuel passage formed in the body and the other end of the passage defines the outlet of the fuel passage.
