Abstract
A booster equipped carburetor in which the venturi bores in the carburetor have an enhanced drop leg booster therein. The drop leg booster has a venturi orifice and a “bent” channel member. The channel member communicates fuel to the venturi orifice and positions the venturi orifice below a second end of the channel member within a venturi bore of the carburetor. The channel member preferably has smooth sides to assure consistent flow without undue turbulence.
Claims5
A method of forming a drop leg booster for a carburetor comprising the steps of:
- a) forming a blank booster having a leg portion with a first and a second segment, said first segment forming an angle relative to said second segment, said first segment having a die-cast formed channel therein, a first end of said die-cast channel extending partially into said second segment, said second segment connected to a venturi orifice;
- and,
- b) drilling a channel through said venturi orifice and said second segment to form a channel connecting with said first end of said die-cast channel.
A method of forming a drop leg booster blank comprising the steps of:
- a) closing a die-cast mold, said mold shaped as an exterior of a drop leg booster having a venturi orifice and a leg portion;
- b) pressing a core pin into the leg portion;
- c) filling said mold with a chosen material;
- d) allowing said material to harden;
- e) removing said core pin;
- and,
- f) removing the hardened material from said mold.
