wet yes, drowned no!
The engine is upside down (as it was on the test stand). I used the primer bulb to suck some gas into the carb and my guess is that I flooded it from the get go.
The primer bulb should not flood the engine. Its function is to fill the carb passageways not to put fuel into the engine. The choking (creating a vacuum on the intake is what allows fuel to pass the internal needle (check valve)
RCIGN explains carb functions to where I understand you may want to spend some time searching. A starter:

Check your plumbing on the primer bulb. Shorter, side port on the primer bulb goes from the top of the carb to the primer. When you press the primer, the fuel should go from the tank clunk fitting) to the bottom of the carb, then from the top of the carb to the primer (short port) and then from the primer long port to the return to the gas tank. Any leaks in the lines will prevent it from working.

You need to get a wet thumb or plug the spark plug.
