ABSTRACT:
An attachment for a fuel carburetor possesses a fuel inlet, a needle-and-seat valve disposed in the inlet, and a float attached to the needle-and-seat valve. In one embodiment, the attachment is placed between and is in fluid communication with both the float bowl and the metering block of a typical carburetor. Fuel is pumped into the float bowl and the attachment in parallel from the fuel pump. The float in the attachment rises and falls according to the level of fuel in the interior of the attachment and float bowl, and thus regulates the position of the needle-and-seat valve, which in turn regulates how much fuel is pumped into the attachment and float bowl. The attachment is also provided with a device for injecting a spurt of fuel directly into the metering block to avoid lean fuel conditions when the throttle is initially opened. In an alternative arrangement, the float bowl and attachment are made as one integral unit. In another embodiment, two attachments and an end cap are mounted on the metering block and the float bowl is not used.
