Abstract
A process for adjusting carburation in a bowl-type carburetor having a main fuel jet for directing fuel to be mixed with air includes moving a needle into and away from the main fuel jet orifice. The needle is threadably inserted through a bowl plug of the carburetor, and moved into and away from the main fuel jet orifice by manually actuating a knob operably associated with an end of the needle extending from the carburetor, allowing the adjustment of carburation without carburetor disassembly, and even while the vehicle is moving.

A process for adjusting carburation in a bowl-type carburetor having a main fuel jet for directing fuel to be mixed with air, comprising the steps of:
- positioning an adjustable orifice plug generally opposite an inlet of an orifice of the main fuel jet, including threadably inserting a needle through a bowl plug of the carburetor and positioning the needle in alignment with the main fuel jet orifice;
- and
- moving the orifice plug towards and away from the inlet to alter the amount of fuel permitted to flow through the main fuel jet orifice.
A bowl-type carburetor, comprising:
- means for positioning an adjustable orifice plug generally opposite an inlet of an orifice of a main fuel jet configured to direct fuel to be mixed with air;
- and
- means for moving the orifice plug towards and away from the inlet to alter the amount of fuel permitted to flow through the main fuel jet orifice;
- wherein the positioning means includes a needle threadably inserted through a bowl plug of the carburetor so as to be in alignment with the main fuel jet orifice and movable into and away from the main fuel jet orifice.
A bowl-type carburetor, comprising:
- a main fuel jet having an orifice for directing fuel to be mixed with air;
- an adjustable orifice plug positioned generally opposite the main fuel jet;
- and
- a plug positioning mechanism associated with the orifice plug, for actuating the orifice plug to selectively alter the amount of fuel permitted to flow through the main fuel jet orifice;
- wherein the adjustable orifice plug comprises a needle movable into and away from the main fuel jet orifice for altering the amount of fuel permitted to flow therethrough;
- and
- wherein the needle travels along internal threads of a bowl plug of the carburetor into and away from the main fuel jet orifice as the plug positioning mechanism is actuated.
