Was looking in langs for Kingston l4 carb parts will order needle seat and gaskets today but what is the cork plug for?
Ronnie I think that gives a cushion to the brass flapper in the carb it fits in that screw above it
Forgot send a P.M. to this guy he does line drawings of everything "T" related and I know he posted a drawing of that carb a while back
Martin Vowell's drawing of the Kingston L4 carb is in this thread: http://www.mtfca.com/discus/messages/331880/375808.html?1374735625
Ronnie, trim the plug down as much as possible as it is way to long. It is just a cushion and if left to long it will keep the carb from opening up as it should. KGB
