Think I found out why my passenger side exhaust manifold is turning yellowish white (too lean) and why my truck has no power... the passenger side of the carb isn't squirting gas!

What would cause this? Anything I can do while the carb is on the truck?

It's a 1406 btw.

You could try some cleaner but most likely you will probably be pulling it for cleaning and rebuild.
