If it’s been a few weeks, I use a squirt bottle to fill the front bowl. That helps prime things.

His should be a quadrajet, no bowl vent tube.

The carb should have a working choke. Pump the pedal once to set the choke and then crank until it fires. If the gas has bled back to the tank, it can take a while to get it back. If it hasn't fired after 20 seconds, pump it once again then crank.
A good maintainer should be able to keep a healthy battery near peak and allow it to crank that engine for at least 3 minutes. If not, you may need a new/better battery.
You may want to invest in a decent jump box too, for times when a battery wears down prematurely. I've had one for several years and it has saved me many times.

I'm no carburetor expert but I thought the tube at the front of the primaries on the 67 Qjets was a bowl vent tube. I've poured some fuel in there to start a dry engine and it seemed to work?

The wire on the accelerator pump arm that lifts the rubber stop is the bowl vent. The tube seems to be over the enrichment needles in the jets, so pouring gas in there would get into the intake to prime the engine, but I don't know if the gas is actually going into the bowl. I'm not familiar enough with that particular carb and tube.
