carb bowl enrichment well will not clear

I have 1 bowl that just wont clear. if I fill it with cleaner and blow compressed air into the well in the wall I get a steady stream of air bubbles. just can not get the spray to blow through the hole and blind me like the others
soaked it for an hour probed it with tiny copper wire. heated it up.

any Ideas on how to get the passage clear

 

I pull a single wire from a large wire brush, straighten is and use it to poke through the hole in the bottom on the well. It takes some fiddling to get in in there but it will work. Or if you have guitar strings they will also work.

 

Have you tried boiling it in some water and lemon juice or something of the sort?

 

got it cleared did the lemon ade poked at it nope

soaked it in berrymans for another day took the thinnest wire from a brush straightened it then heated it ,streched it out to make it thinner. glued it into a wooden q tip .

used a bent copper wire to poke and scrape from inside the bowl took the q tip and twisted down the well got it into the hole and worked it for 20 minutes .
also shaved down the tube on the carb spray so it would fit into the bowl hole. sprayed across the room.

 

Think i mentioned copper wire at one point to another member for this issue... Fiddly, but bang! A dube, a beer, an 20 minutes can save a float bowl!

 

it was telephone wire that I used. got a nice hook in it .I did not realize how far in and up the lower hole went.
