So the saga continues

I took the truck for a run to the hardware store today and at 10 miles out of 14, she stuttered and stalled. I popped the hood, tapped the carb a number of times and it fired up. So I thought I had figured out the carb issue, but clearly all the bugs aren't out. Is it fair to say that with the last two stall outs, after tapping the carb and it starting up that it's a float issue? I've replace the float & needle as part of the carb rebuild, so it shouldn't be hanging up. Any thoughts or suggestions?
Thanks!
