Throttle full open, spring or autumn driving.
The spray density is much lighter.
Note: In addition to the hot-air pipe as in Figs. 10 and 11, which
heats the air entering the carburetor, a hot-spot attachment is
provided on the intake manifold which heats :he mixture as it passes
through the in-take manifold to the cylinders. The hotspot is heated
