Holley 4160, vacuum secondary ?'s
after thinking about what a couple of you said a few weeks ago, it does actually sound like my secondaries aren't opening...
I checked for vacuum leaks and found none.... soo my question is, where does the secondaries get the vacuum to operate??
Is it throught the carb body or does it need a vacuum line connected somewhere???
I pulled the carb out of the box last fall, put it on the car used one of the vacuum ports to run the vac advance, and plugged the rest...
was this not correct??? the old factory carb has a short vac line that goes from the top/passengers side of the carb to a port by the choke housing, but the new carb does'nt have those ports...
help pleeze, i am really confused....
