Yep. I actually had 2 different problems with my 2 brl. The bowl would empty over time and it would leak fuel and flood the engine after run. Then it was hard to start.
I changed a few things that cured all my problems. A thick base gasket for a later model keeps the fuel in the bowl cooler which probably helped. A air pocket in a see through fuel filter mounted horizontally was making me crazy too. Idle rpm was changing with the cycling of that air pocket. A new fuel pump and relocating the fuel filter vertically in the line near the pump was another change I made.
In the end I think the accelerator pump linkage adjustment was the main culprit. The pump rod wasn't returning quite high enough to open the bowl vent.

a thicker base gasket is big help with hot starts....this so called gas we get today is has a lot alcohal in it witch causes it evaporate faster on car with carburators and to boil out went engine is shut off hot.
