I have a 1978 Hawk TII with a VB-21B carburetor that I am trying to clean/rebuild because it was sitting for three years with fuel in the carburetor and it runs very poorly. I was able to remove and clean most of the jets and jet needles but am having trouble figuring out how to remove the slow needle jet. It looks like the slow needle jet is pressed in and I'm not sure of the best way to remove it. I'm referring to the jet needle that is normally covered by a rubber plug. Any help/suggestions would be greatly appreciated.

Does the pilot (slow) jet have a screwdriver slot in top? Can you take a picture and show us what things look like?

The slow jet is "not removable". It can be done but pretty much always will destroy the jet. The slow jet size is generally not an issue, just ensure it is clean (reference the above mentioned tutorial).

Problem solved. I removed the pilot jets using a drywall screw, a torch, a pair of pliers, and a hammer. They are still in very good shape with a little smoothing on the end using a file but I was able to find replacements and will use those. One was a little clogged so I'm hoping that was my problem. I also noticed some small holes and creases in the air cutoff diaphragms and will replace those as well.

It looks like those will work. Let me know.
