I have a Murray 300 Series push, Briggs and Stratton motor. Some long wire apparently just cracked off. It apparently was part of the process that starts the engine when you pull back on the bar on the handle as you pull the cord. Is there any way to start it up without this? Probably not, as stopping it would be an issue. Looks like it cracked off so it is probably not an easy fix; may need soldering? Thank you.
