Rebuild/ Identify

Hey Everyone,
I have had some small issues with the acceleration on my car since i bought it lik if i step on it to quickly it will sputter and die, and recently the carberator isnt getting anygas on startup but runs fine once its started so I'm thinking its rebuild time. The problem is that im not 100% sure what carb i have, Im 99% sure its a rochester. Its the stock on a 71 dart swinger with the 318, I'll post some pictures on it and there is a stamped number thats either 70441180 103 1 1 or 7041180 103 1 1 i may have taken it down wrong, But I'm new to Carbs and working on them and i was wondering if anyone knew of any handy guides to rebulding them.. Driving a car older than me makes working on them a learing exsperiance.<sp>
Thanks
