What else could there be?? I poured gas into the cylinder and best I could get out of it was a backfire no start and run partially and die .... nothing!
 
"best I could get out of it was a backfire" That may be your problem. Take off the cylinder head and see if the valve(s) are closing. At Top dead center with both valves closed, try to turn the valve. if it easily turns, the valve is stuck open. If so, remove the valve, check the gap,grind down the valve gap down to spec as needed.

OK at least I have something to try, I figured i would have to go deeper, now any tips to where I get the engine specs?
 
You will need the model number, if it's a tecumseh flat head, it's usually stamped onto some sheet metal by the spark plug
