ok I bought a 580ck it’s been sitting for an undetermined amount of years outside in the brush I’ve looked it over they covered the breather instead of the exhaust but there isn’t any signs of water in the oil I order a shop manual and I’m gonna try to fire it up next weekend I’m just wanting to know what precautions should I take I’m hoping it will start and load under it’s own power or should I maybe plan on taking another machine with me I’m new to the old case machine but not afraid to learn any help is appreciated
