nipple on the intake
use carb cleaner, and a bailing wire, sold copper wire, or coat hanger wire, never use a drill
or buy pipe (smokers pipe ) cleaning brushes. soaked in carb cleaner.
hose 28, nipple. Dash pot VSV vac, source. it's a hard vacuum port.
id not drill it , it might take a 90deg turn inside, we don't have xrays, the manifold.
there are no orifices here, its just a casting and drilled passage. does the nipple unscrew (hex base.,?)

The hose goes to the bottom of the throttle opener valve. I first tried carb spray and compressed air with no luck.
Next I took a small pick and it seamed pretty solid. Is this like this from the factory or do I need to try to drill this out.
Thanks Jason
