Can 18 months of non use of lawn mower cause a blown head gasket? Answered
I just purchased a small lawnmower at a garage sale and the owner said he had not used it for 18 months or longer. I put fresh gas in it...changed the oil and spark plug and it started right up. After about 5 strips of cutting with no problems...it started blowing out smoke and the exhaust got very hot. Is that a blown head gasket and could the sitting idle for 18 months cause the gasket to deteriate?
