What did you take a pic of? You are supposed to degree camshafts with a degree wheel, not take pictures of them. At the very least you're supposed to line the marks on the timing gears up and you should be fine. No pictures needed there.

If this is a radical cam with long overlap/duration, especially from what you had before, your carburetor will not idle correctly. Is this a long duration cam with a lot of overlap? If so, check to see where your idle screw is at. Do you have to back it in a lot further now to keep it running? if so, you're not running off the idle circuit.

Assuming you did the cam install correctly and it was broken in correctly (no wiped lobes or lifters), and no vacuum leaks, I suspect the carb is not calibrated for this cam. Check your timing and make sure it's where it's supposed to be, then look at the carb. What kind of carb do you have?
