Volvo Vacuum Advance Problem

[wbhoss]

Hi there,
I have a 1972 19' Reinell with a Volvo AQ170A with a vacuum advance distributor. There doesn't seem to any vacuum ports to plug it into. The motor runs great at an idle, under a load it dies. I think it's not advancing.
Does this need to plug into something that I'm not seeing?
Do I have the wrong distributor (though I've seen this setup on a similar boat with no vacuum ports)?
Or is there something else that I am missing?
Any help is appreciated, I'm stumped!
Thanks!

It is the correct distributor, however, the vacuum advance was only hooked up on the 165's, not the 170's

Thanks Don,
The 170 is stamped on the block, so I assume from what you're saying that it is just not hooked up?
So if this is working correctly, what else would make the engine bog down under a load - the carburetors?
Too much fuel? Though it starts right back if it dies (though I can control that through the throttle).
