72 360 first start question

So yes I mean that the spark rotor ends up pointing between #1 and #3 when I rotate the oil drive gear CCW. I will try that reluctor gap test tomorrow. Also yes I'm retarding the ignition timing (rotating the dist.) to bring the idle down. I don't hav a tach hooked up but I think that's my next move. But as I back the idle down by turning my dist. I get it to a point where it'll run steady but it's still too much for and idle (12 deg. BTDC on the timing light) and it's literally one more tiny turn of the dist. a degree or two at most and all of a sudden it sounds like a good idle but if I don't keep hitting the throttle every couple seconds it'll sputter and die. Also Yes I'm setting the initial timing with the vacuum advance line disconnected and plugged on the carb. when I connect it, my rpm's go way up and then I can back down the ignition timing further by turning the dist. but it's still the same thing. I can't get it to that sweet idle spot.

Two things.

Are you connecting it to ported vacuum?

If you are sure about that,

Do you have a leak in the hose, or in the vacuum advance can? Keep in mind just cuz it's new doesn't mean it's good.

The idle should not go up just connecting the advance canister.
