I have a 9n that runs fine at low rpm but coughs and sputters at higher rpm/power.

The old fuel bowl valve was missing the screen on top and clogged so I replaced it. Now I have the problem where if I tighten the bowl up to where the gasket seals and there is no leak, no fuel flows at all from the tank when I open the valve two turns (or more). I did this with a dry fuel bowl so I could see what was going on. If I loosen the bowl to where fuel flows down freely, its so loose it leaks at the seal and runs down on the engine block.
