The needle valve I am talking about shuts off the flow of fuel into the
carb bowl by pressing against a brass seat which is part of where the
fuel line attaches to the NT carb.
Took apart the carb and the float was filled with gas.
Did notice the filter looked like **** and on an older one I built the line had hardened. Going to maybe start putting on metal inline filters and Thermo Tubing over fuel hose for cars.
