If the motor starts fine as long as it is cold I doubt it is an electrical issue. I think you were on the right track in the first place. The motor sounds flooded with fuel. Do you have an electric or mechanical fuel pump? If you have an electric pump shut the fuel off and let the motor run out and die on its own. Then turn the pump back on and start the engine. If it starts OK then you know what the issue is and you can adress it. You can also remove the carb after a few minutes and see if there is fuel laying in the manifold after shotdown.
