Ok, got the dwell set correctly, and now it will idle without help, at least at the curb. There is a louder than normal hissing sound coming from the aft carb, and looking down the barrel, it seems quite wet, the fwd carb is dry. also notices that if I cover the aft carb with my hand, the engine rpm's speed up!? not so with the fwd carb.

No arrow on the timing light to indicate direction, still no clue on that one.
