George, he did put in fresh gasoline.
The next thing to do now is to put the new battery on a battery tender while you wait for warmer weather. The start attempts drain a lot out of it. Put a few ounces of carb cleaner in the tank for good measure.
Make sure you're using the choke to start it, and wait for the warmer weather to try it (disconnect the battery tender first). Do not give any throttle when starting.
If you can't wait for warmer weather to try it again, you could aim a forced-air space heater (at the low setting) at the engine for an hour or so, from a respectable distance.
The other thing that's been mentioned before is check your air filter and exhausts for mouse nests and such.
