My experience, for what it's worth, is that when Coxes sit for a while the fuel passages in the tank backplate get either partially or fully clogged. This can be either corrosion OR gummed castor oil.

If this is the case the needle will be extremely sensitive.

To cure gummed castor, pull the backplate, take the fuel hose and needle valve off, soak the plate in acetone for a half hour or so. Then use a very fine wire to probe the passages and soak it for another half hour. Then probe it again with the wire, and flush it with fuel.

If it is corrosion you'll need to get some very small drill bits to clean the passages. The bits will also make a much faster job of cleaning gummed castor.

Cured several this way, the 02s seem to be even more prone to this than the 049s.

HTH.
