Have a Craftsman 20 hp 42" lawn tractor with electric start. The tractor was running fine, went to refuel and then tried to start. Mower would turn over but will not start. Have mover in neutral, blades disengaged and sitting on the seat. Checked the fuel flow, running fine. Checked the fuel filter looks fine. Checked for spark, had wire disconnect while cranking, didn't see any spark.
Any ideas .

Resolved the issue. Even thou I had spark it was not strong enough. Charged battery over night and tried starting next day. Mower started fine...
