Hello! This morning, while I was clearing snow,the engine on the snowblower suddenly quit for no reason, and refused to restart. After checking that the engine was getting gas, I pulled the plug. It looked fine, and produced a spark. When I compared the spark to a new plug, it seemed only slightly weaker. Since I had no idea what else could be the problem, I put the new one in and cranked the engine. It started on the first pull!:dunno: I have never heard of a plug quitting with no warning while the engine was running, and still having a spark. Has this happened to any one else?
