Weber carb

[SJagGo@aol.com]

Greetings,
I'm getting ready to install a used Weber carb.  It's a downdraught twin 
progressive model with manual choke.  I can't find a definite place for the 
vacuum advance tube to the distributor.  It looks like there may have been a 
small pipe break off directly below the choke (there is a vent hole below the 
throttle into the throttle bore).  Is this the correct place for this?
