Riding Mower With New Carburetor Won't Start?

I have a 2002 Wheelhorse mower, model ch15s-44533, 315-8. I cannot get it to start. I replaced the ignition module (magnetic), spark plug, battery, and carb kit. It will turn over, but won't start. It was my dad's tractor and he's no longer here for me to ask. Please help.

Hardiness Zone: 7b
