Have you tried removing the spark plug to see if it is sparking?
Have you verified that that fuel is flowing past the fuel filter (I think there is one).
I had an issue once with a small motor...wouldn't start for anything. I ended up disassembling the carburetor. I found what appeared to be like a little stone clogging a jet. Cleaned, replaced and reassembled and the motor fired right up.

Are you flooding it constantly by trying so much?
Just trying to think of stuff to help!
