Generally the vac advance needs to be hooked to a ported source. It takes all that extra advance out at idle, it's not needed there, not trying to start an arguement, just my experience.

Check all the little details, we've all been bit at least once...

I've seen carb base gaskets that just barely made a seal, when installed, and a little heat and time made them leak...When you start using aftermarket parts, there is no written book to guide you, just your skills and emails...
