Start M110 after long service life

Hello together, I bought my C123 280CE automatic as a restoration project, I’m pretty new in the oldtimer game The stand has been around for a good few years and wants to get it to run again. The engine is supposed to be absolutely undemanding and robust, but just want to be safe at the start and do not make any faxes. So can I start it without problems after a few years of service life or should you rather take a few steps? (: Many greetings Noel
