I just did this to a 380 that was so bad that you couldn't get enough throttle response to make it around the block. Now, at idle, you can't even feel it running. I would spray carb cleaner where the intake mates to the head while the car is running. If you have a significant change in idle this may be your problem. I agree with duxthe1, if it's a fuel problem it can get very expensive and hard to diagnose on the old CIS systems.

I think that this is a great place for a hobbiest mechanic to start. These are, for the most part, items that should be replaced on any car that's been sitting for this length of time, regardless of running issues (along with ignition systems that Husky mentioned above).
I've seen a lot of videos about the Bosch CIS system, and I certainly get how it works. But I understand that diagnostics are a totally different ball game. I'll perform the above items, and if nothing changes, I'll talk to a professional.
I plan on getting my hands on the car in late November. I'll let you all know how it goes!
