Squirters
There are two types of squirters; regular and tube type. The tube type squirters are easily identified
by the short tubes extending from the exit orifice of the squirter. The exit orifice diameter of either type
squirter controls the duration of the pump shot. The smaller the diameter, the longer it will take for the
complete volume of the pump to discharge. A larger diameter discharges the pump’s volume quickly.
This is assuming no changes in pump cams.
Electric chokes are included on VE series carburetors
–
available for mechanical secondary units.
Complete the following steps to wire and tune the electric choke:
1. Run a wire from a switched +12V source to the connection on the pod cover marked with a (+).
Run a second wire from the terminal marked (-) to a good ground. See Fig. 21.
Figure 21 Figure 22
2. There are two primary adjustments: the fast idle speed screw and the choke timing. The choke
idle speed screw controls how far the primary butterflies are open when the choke butterfly is
closed or partially closed. It sets your fast idle. The screw is located on the bracket that is slipped
over the throttle shaft, behind the choke pod (Fig. 22). This idle can be increased by turning the
choke idle screw clockwise, or decreased by turning it counter-clockwise. It is important to note
that when the choke butterfly is open completely (vertical up and down), the choke idle speed
screw must not be holding the primary butterflies open at all. In other words, when the choke idle
speed screw is in the deepest cut on the fast idle cam, it must not be hitting the fast idle cam.
