Rich a lot of guys think running a tank low causes dirt and water to be drawn up.Not true the pickup is always near the bottom of the tank.Take it off and have a rad shop clean it thats the only way to do it properly...FRED

You should also flush the lines and fuel pump. I had a similar problem on wifes Mazda from getting bad fuel from the bottom of a station tank. We dropped the tank, cleaned it, ran new fuel through the lines and pump and still had problems with crud holding open the needle valves. The Finally solved the problem by changing carb to Weber and adding a centrifical filter between the supply line and fuel pump. Car ran better and had better emissions tests than with stock carb! Inline filters won't catch the small stuff. Good luck.
