For the Honda Tech's. What is the button on the side of carb right above the bowl drain screw. I looked on the carb diagram and it looks like it says it is a "Pump Set". What is this and what does it do?

It is the primer botton. Its really only needed in extreme cold weather (never used mine). Its just like the one on a lawn mower/weed wacker.

What does it do that the choke won't handle?

 

[Truegrit]

It puts/forces more fuel it the cumbustion chamber to get it started. The choke allows more fuel to flow into the combustion chamber. If that makes sense.
