The inner life of a Weber DCOE

Not much fiddling around Triumphs today. It's freezing cold in my garage at the moment, so the better option is staying inside the house. Unfortnately the battery of my daily driver went flat, so I had to change it for a less older one. Not a pleasure job to do out on the street. Especially not when it's snowing... Stayed in for the rest of the day, finding out about the inner life of a Weber carb. It starts making sense to me now...... It all seems very complicated which isn't actually.
