Yanking hard at idle???

Those are the cam specs. I can get it to idle 800ish, but the timing advance at that point (no vacuum) is approx. 30 degrees, which is crazy. I verified with a vacuum gauge and I had like 17hg there.

If I drop it down to 20 degrees with the vacuum disconnected, it gets choppy and drops significantly when put into gear. That's why I've been running manifold vacuum, to get me some advance in the canister.

I'll richen it up with the bleeds a little bit more and see where that gets me.
