SOURCE: Mower wont start.

I have a 927 series rider and just put a new battery,and spark plug.Has spark and still wont start. What else can I try?

SOURCE: No spark at plug

Hi, I can see you posted this in April, so you may have sorted it by now!..? Is your problem that it will not start? If so and you have checked that the air filture and spark plug are OK, then you should make sure that all four lights are on, on the dash. Also you need to make sue that the black flap at the back directly behind the seat is pressed down properly. If it is up slightly it will stop it from starting as it is a safety feature. It has some sort of trip swith on it. I hope this has been helpful.

If the mower starts and continues to run after injecting, you may want to make sure the choke is working properly. If the choke plate is not closing all the way, it will make cold starts difficult.

Testimonial: "thanks for the help the choke was open just a little"
