I did a tune-up on my truck today and everything went pretty-good. We got to the vaccuum test but there was no vaccuum suction from the carb. I asked my dad what to do and he suggested I use q-tips to clean the opening and a copper wire to remove the blockage. I did that and still no vaccuum. So, now what do I do? Should I use the compressor and blow it out or do I need a new carb?

I'm still shooting for passing Aircare (emmission testing) in 2 weeks. How does no vaccuum affect the engine? I don't really understand how it works. The engine runs great but when we reduced the rpm to 475 in the manual it was not too happy so we put it back to 600 for now.
