Cylinder not firing

The spark seemed strong to me?! I did go and buy plugs, wires, and a rotor just in case I needed it. The spark seemed as strong as others that I checked.
There might of been a chance of over-revving. On the way out to the show the road was wet from rain the went through. I did have some spinning issues as a result. I don't do any excessive burnouts as I don't really want to break anything! Lol!
Thanks Inertia...anything helps!
