85 won't idle
 

Today I picked up an 85 with a 12a. It's had a few things done to it, so I don't know where to start. I guess I'll start with the problem.

The car won't start unless you spray starter fluid into the carb. And then when it starts, it won't stay running.

Some things that I have noticed that are different, is the electric radiator fan, and the Holley carb in it. I plan to rebuild the carb, as I imagine it to be the issue. First, I want to know if this is the correct carb. The markings I have found are "Holley 6R 6910 List-1850-4 0882" It looks like it has an electric choke.

Also, besides rebuilding the carb, and changing the plugs, what else do you suggest I rebuild/replace tomorrow?
