I too have a spare 87+ carb and a device box. I don't want to use it either.

I "could" check that solenoid. I "could" swap in the other ECU. I'll think on which would be quicker and easier. It's cold out there (for this AZ-acclimated) guy!

Grrr, I want this thing to RUN! I need to move on to my '95.
