I have a 44" Hustler with a 18 hp Honda v twin that has no fire to the plugs. Has any one ever had this problem and where should I start to look? It didn't just start not having fire it was a slow process. It started one day and from then on it has gotten worse. Now it just dossen't start. Put new plugs and still no fire. (PLEASE HELP MY GRASS IS TAKING OVER)
