I have a Weber DGV with Electric Choke on my 68 spit that had leaky
SU's. The electric choke works fine. It works by using the
electricity to heat the wire of a coil. This coil is connected to
the choke and as the wire slowly heats up, it gradually turns the
choke off. When it cools, the choke comes back on. Once you install
the carb, you hook the wire up to the choke. This should be a wire
that is hot only when your switch is on. Then you can adjust the
time the choke stays on by loosening the screws and twisting the
black plastic electric choke body itself. It took me a while to
figure out this part. I suppose a water based unit would work well
too, but I'm not sure if they can be adjusted like the electric one.
Since installing the Weber DGV I have had many years of happy driving
with little if any carb adjustment.
