how to awake a 914-6 engine correctly after a very long time? Options

[Gustl]

I already posted this question in a german froum, but I'd like to get more opinions on that topic

it's about an original 914-6, which got a complete enigne rebuilt (incl. new cylinders, pistons chains, ...) 20 years ago
then the owner drove it for about 3k miles within the next 7 years
from 1994 on, the car was stored away and never started again ...

so, how to awake this engine correctly, to avoid and long term damage (IMG:style_emoticons/default/confused24.gif)
some told me there might be problems with the carbs, probably any rust inside the cylinders and bearings and, and, and ...

any comments appreceated (IMG:style_emoticons/default/beerchug.gif)

I also would like to chime in with my past use of PB blaster on hibernated engines.

Spray, let sit and turnover by hand, repeat. Change the Earl and follow the Slits and others suggestions above. The PO of the engine I run today. Just left the car outside in the rain, snow and sun for eight years after it quit for FI issues. True it was just rebuilt before it quit. Long story short. I can tell you that it still runs strong today, has great compression and runs great.
