So you are assuming that the starter and solenoid are on the same unit, like on a Kohler or a Kawasaki? Which would be good to know if one would give decent advice.... But of course anyone in the business in the last 15 years or so, would tell you that a starter/solenoid combo assy costs about the same as just the solenoid by itself, but it is always good to be enlightened as to the brand/model/spec/etc.......
