Carter YF carb issues, possible a "fuelish" mistake.

[Mark J]

Ok I finally got to this... sorry life gets in the way of my jeep sometimes, dammit.
Replacing the needle and seat with the "springy" one seems to have solved the issue.
This seems quite trivial but the fuel sloshing seems to have stopped. Still I'd think this was a combination of float level/drop and the needle/seat but I really didn't adjust the float all that much. Well anyway... so far all is good.
