Hello I just bought a used mower the other day from someone and when I picked it up started and ran just fine other than a weak battery. Once I unloaded it from trailer and attempted to start it was a no go. You could smell gas so just assumed it was flooded. Pulled the plugs and just replaced since they looked questionable but still no start. Plugs are getting plenty of fuel but even with plug removed from cylinder and ground not getting any spark. I bypassed under seat safety switch think this may be bad but still no luck. I am not too familiar with small engines so any help would be greatly appreciated.
