Hello good, first of all thanks to those who can help me and I feel if I write a lot.
I expose my case:
I just got out of a quarter in my grandfather's old factory, a Lombardini LDA 91 of 3000RPM engine, it has been stopped for about 30 years, it was kept working, it was used in the grave and the only one moved all the machines through pulleys. The fact is that since I was little every time I entered that room I was dumbfounded with him and I would like to wake him up and make him turn. But since I have no idea of engines, I wanted to consult before, no piece, screw or thread is missing. And I would like to know what I have to do now before hitting the pull, what to do to start it again, an eye that has been stopped at least 30 years.
Greetings and thank you very much in advance.
