Abstract
A variable fuel admission carburetor is provided including a piston and cylinder that are mated concentrically, and coexist in a carburetor chamber. The cylinder includes a longitudinal slot which allows varying amount of fuel into the carburetor. Through the relative longitudinal movement of the piston in the cylinder, the exposed length of the slot is varied, thereby varying the amount and rate that the fuel enters the chamber.
