Was riding quad, got to garage and was idling for a little bit when it shut off. Won’t start after that, has spark, new plug. Put a couple drops of fuel in the cylinder to see if it would run on that and still won’t start. Put my finger on the spark plug hole and turned it over and it did blow air past my finger. Have yet to check the carb but figured it would run off the fuel I put in the cylinder. Any input ?
