I echo Milton's advice. An inline plastic body fuel filter is fine for diagnosing fuel flow, but replace it with metal for the long run. I've also cut the pickup end at a 45 and hose clamped some steel screen on the end to serve as a trash filter.
Dave ================= Frank's correct. The sock in the gas tank could be coated with crud and blocking fuel flow. If that's the case, simply throw the sock away and replace the inline fuel filter you should have up front to protect the carb. Actually, an inline fuel filter should be ahead of the fuel pump to protect it also. Milton Schick
