So, I bought this motor a few years ago from a trusted source. As it turns out, it was originally built a several years before I bought it but never paid for. The builder hung on to it end then sold it to me. I knew the person it was built for so I had a good idea of what was in it. Do I need to do anything special to this motor, other than priming it, before turning it over for the first time? Friends have raised concerns that it's been sitting for so long (literally like 12 years on the stand!) but the builder told me this won't be a problem. Naturally I'm worried. Your thoughts?
