1970 Ford Ranchero Car won't start, gas coming out of carb

Hello - I have a 70 Ranchero (351C 4V), with a Holley 750 Carb (with manual choke), I ran out of gas the other day, and in the process flooded the engine trying to get it started after I filled it with gas. I had no starting fluid so poured a bit of gas into the carb, first time I have done this. After the car sitting for more than 24hrs, I attempted it to start again, only to have the engine (carb area) catch on fire. I was able to put it out, but the reason was because gas was pouring out of carb. Did I ruin it by puring gas in there. I am scared to try it again, but I know it's becuase the engine is flooded, this has happended many times before and I always get it started. But because gas was pouring out of the carb this time I am scared to try again If I do want to try it again on my own, how long should I wait before I try to start it. I have a on/off option with my fuel pump, will that do anything?

On top of this, at one point I pulled key out of ignition, but the power stayed on in the car, this is the first time this has happened. Battery died as well, but I was able to jump it so that it can get some juice. Then I read something about when an engine is flooded, it will not let the starter function correctly. Please help! I don't want to have to spend an arm and leg to get this fixed. Any suggestions?

Thanks for your time and help!
