Re: Car won't start without priming carb

During carb manufacturing passageways are drilled through the outside of the carb to a spot inside to create an internal passageway for air/gas.....the outside hole in the carb body is sealed with a soft metal plug; I believe it's called a welch(sp) plug. These plugs can leak or fall out. Might this be the hole w/o threads you speak of? Hope this helps.
The fix is pretty easy, if the plug is still there and leaking use some JB weld to seal and afix the plug.....
If the plug is gone I have used JB weld to fill and seal the plug hole. As big Kev stated "a picture would help"
