I set the metering slide bar to use the largest opening when using the foam gun and as far as measuring soap goes I tend to use the glug-glug method. 
How to adjust the metering slide bar
Your Marine 31 Foam Gun comes with a metering slide bar that allows you to adjust the concentration of soap solution to water.
6 hole stops on the top of the metering bar
Looking at the metering bar from the top you'll see 6 equal sized holes. These are "stops" that lock the metering bar into position with the use of a spring loaded check ball inside the mixing chamber.
You can twist the metering bar sideways to push it in or out of the mixing chamber when choosing a solution level and then twist it back to the upright position to lock it into place.
5 graduated holes on the bottom of the metering bar
The smaller the hole the less soap solution that can be drawn into the mixing chamber and thus the less foamy suds. Just behind Nick's finger, opposite of the hole stops on the other side there is no graduate hole, this is last section is solid to enable you to switch to just water for rinsing.
The larger the holes the more soap solution that can be drawn into the mixing chamber and thus more suds will be created.
