truck doesn't start

[theredmeadow]

its a 70 c10 5.7l 350 regular/stock carb?
it's cranking but not turning over at all. it's been starting since yesterday and even last night but it's been having more and more trouble starting lately. cranking a lot just to start. its warming up here and shouldn't be a problem. well i noticed something weird about the choke? am I missing parts? here are pics of the carb? is there a missing spring on the choke? are there any pics you guys can post of what it's supposed to look like?
this is my daily driver so I need to get it up asap. you guys are geniuses so I know u can see the error.
