Back of a Stihl FS-110

I came across a Stihl FS-110 trimmer that would run, but wouldn’t idle. At first glance everything looked as it should, but once my finger touched the carburetor primer bulb I could tell something wasn’t right. Rough edges had developed on the outer surface of the primer bulb created from cracks and breaks in the plastic, which will naturally occur in plastics over time. As soon as my finger applied pressure to the primer bulb it collapsed underneath my finger, and the problem with the trimmer not idling was found. It just goes to show how important a visual inspection is in the repair process.

 

 

 

John 3:16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
