Alright, we've tried just about every position you can stick that distributor, and still nothing. i found a dimple down by the gear on the distributor, and the only verticle mark i can see to line it up with, on the outside of the housing, puts the distributor pointing almost straight forward, not back towards the firewall. if i line the dimple up 180 degrees to that, then the distributor points towards the back of the engine, but that didn't give any results either. what am i missing here? could you give a better description of the things you just talked about, like the tunnels, towers, verticle marks, and am i looking at the right "dimple"?
