1972 dart 318 problem starting

not saying this is a fix but wire that choke wide open and see what happens. I have ran a 600 Holley and a 750 Edelbrock and mine starts every time, it does need a little coaxing untill it warms up though. another thing, plugs gotta be good and timing set right ...fire right up every time. thing is to know what to focus your attention on, and things like timing and carb ajustment go together. Vacuum leaks? hows the intake gaskets etc.? vacuum hoses?
