Awesome.

You should double check the initial timing. Maybe you can borrow a llight from a friend? If you can manage to get it to idle, just make sure you unhook the vacuum advance hose so that you are reading just the mechanical advance by the distributor.

Carbs don't typically cause a sudden change in performance like you have described. They can get dirty and stuff but don't usually crap the bed and leave you limping home. You need to troubleshoot more before replacing/changing anything else.
