Are the bits circled red below vacuum ports??



I beleive they are, but I'm not getting a vacuum reading on my gauges. I have the dizzy connected to one, I have the gauges connected to one on each carb, and the final one blocked off.

Anything to do with my problem?

Could it be a mixture thing? I cant find my compression tester to check if the valves are seating properly, I'll have to look harder!

HELP ME!!!
