I have an MTD 42a707 18.5 hp riding lawnmower. The engine turns over plenty fast, it is getting gas, and has new spark plugs, but is not getting a spark. Does that model have a coil?

If you're not starting and the plug is firing good, it's likely the "anti-backfire valve" has taken a dump. It screws into the bottom of the carb and has a couple of wires on a plug attached. Remove and replace.
