Id just buy a new ht lead to start with if thats what you mean youve snapped. And just takyou spark plug an the fuel should evaporate.
But like thelad abouve said, undo the spark plug stick i in th plug cap an put your thumb over the the end of the spark plug, youll feel a tingle in your finger which id good an neans you have a spark
it doesnt hurt donlisten when people say it does, only hurts on a car haha
