I've been having carb issues recently and wanted to hear what others were doing.

My first problem were my needles sticking open and flooding the motor. I attributed this to dirt getting wedged in there and put those tiny stock filters on top of the seats. I also bought an earls 35 micron filter. My fuel system now looks something like this:

cell -> screen at the pickup -> pump -> 35 micron filter -> brand new regulator -> carb (with tiny filters on top of the seats)

At the last race the tiny filters on the seats clogged about 12 laps in and I couldn't get any fuel to the motor. I'm not sure where this dirt is coming from, as I figured 35 micron would be smaller then those filters. Granted it took 3 races worth of lapping before the filters clogged, but I would rather not have to clean these out after every session.

What setup are you guys running and are have you seen these types of problems before?
