Diagnosing a Potential Fuel Problem

>Cam specs: Unfortunately, IMM forgot to give me my cam spec sheet. It's a custom grind. It's either 238/242 or 242/246 at 0.050".
>When I go for my drive today, I'm going to take a look at the choke. The Holley and Jegs videos are saying if you have problem with cold start up, to dial it back one notch.
>Timing: I don't have a timing light on me to measure initial timing. Like I said, I took it to an engine/dyno shop to take a look at it when I had the misfiring issues with the shop that was building the car. I don't recall what he measured for initial timing. How do I fix rotor phasing?
>Fuel: How would I know if I have extended pick ups in the bowls? Do they vary per model or am I going to have to take the carb apart? I just mentioned a full tank to eliminate the pickup idea. I'll take a look at all of the lines before I go for a drive today. I'm pretty sure this is a returnless system, but will verify.
