Started to work on a friends Holley NH. It's from a new to him 1926 Model TT truck. Over the week end we tried to start the truck but could not. The carburetor was filled with gunk and varnish. This afternoon I got the spray nozzle 6214B out of the casting and it is plugged. I'll poke a wire through it to clean it out. I was wondering what size the hole is so I could run a drill bit through it. Anyone know? Mike

Slightly smaller than one bit in your set and slightly bigger than the next one.

Gee.... is that it? Well, after working and soaking this hard crud, it finally came out. It appears that the head is brass and the stem is steel. It was so dirty, it was hard to tell what it was.


Gently I tried a couple number bits, making sure not to damage the orifice, I found that a #30 will fit the large end and a #53 the small.


For what it's worth. Mike
