It sounds like you have a fuel delivery problem, could be plugged low speed jet, stuck float, or dirty carb.

The broken dead man/kill switch will need replaced. The broken switch has defaulted to off position.... Here is a pic of the tiller handle parts.

Make sure you blew it out really well. Tiny things in there can cause really big troubles. Also, you might be able to disconnect that dead man switch temporarily to get her to start for troubleshooting.

The first thing I would do is see if the spark will jump an open 3/8" air gap. If not go for a prob in the kill switch wiring.
