I have to start it with the pedal to the floor......Doing this helps to clear out the flood with more incoming air. The carb has an internal leak-possibly the float has a pin leak drowning the float bowl.

I don't think the float is leaky, there was no liquid in it when I took it apart.......any other thoughts

Your problem is coming from the carb or you have an excessive fuel pressure
