Yes, I agree that the level in the bowl has some bearing on a loaded engine but what has been pretty much ignored in most of these posts is he cannot get a combustible mixture to start the engine.

The only thing that is germane to starting and idling is shown in that picture plus the pressure differential provided by the cranking engine.

The main function of the venturi is to atomize the fuel. When the throttle valve is closed that function is assumed by the bevel on the throttle plate. That is why it is important to have the correct plate and that it is not installed upside down.

For starting and idling, as long as the bowl has fuel and atmospheric pressure, it doesn’t matter if the float level was set at 1/8” or 1/2”, It doesn’t matter if the fuel line is connected to the carb, it doesn’t matter if the power mixture valve is shut disabling the entire power fuel circuit. So why address everything from the gas tank vented cap to the main jet? It’s irrelevant to this post.

Perhaps I am misreading the question in the initial post. If so I apologize in advance and will slink away. In fact the sun is shining here finally after a week of daily rain. I am going out and play with my tractors.
