Good info brokenhead. I am mentioning what I did because I had this issue on a 2bbl. on one of my 83 Eagles. The seat of the needle valve was bad and would let fuel go back down to the pump and into the tank after sitting for a few days.This was because mainly the carb is generally higher than the fuel tank and fuel tended to run that way rather than into and flood the carb.But like said, there should be some fuel left in the bowl.I could see that a couple of pumps on he pedal and crank overs could use that right up before it catches up with itself and pushes more in from the pump.Like brokenhead said, check the fuel pump, pull the line and use a can or soemthing to see if it is actually pumping fuel out satisfactorily. good luck.( by needle vavle I mean the one that works off the tang on the float and lets fuel in when it drops or blocks it off when the vowl is full )
