The coach starts easy and runs smooth, takes off nicely but when i put my foot in it very little happens-

I ran it with the cover off and watched the carb- secondary not opening. I poked around a bit and i understand it has something to with the choke being fully open.

And there's a vacuum diaphragm in front that does something?

If someone could explain what normal operation looks like i can probably form a more intelligent question.
