High rpm backfire

[tekslk]

Took the old girl out today to warm it up after 10 miles I opened it up it backfired a little threw the carb, I had just put new plugs and wires on in the fall any guesses where I should look or is this from starting and shutting off a few times during the winter months? It got a little better till I got the car home but still had some backfireing in it.
