340 turns over, got spark, won’t fire and run

First things first,
You NEED to fix that fuel leak before something bad happens. I remember warning a guy that was trying to start his car at a convenience store that his carb was leaking around the butterfly shaft and that he shouldn't be trying to start it. I just walked into the store when he came running in saying he needed a fire extinguisher. Hated to tell him "I warned you". Get the leak fixed then check for spark.
