ok, so in a couple weeks i'm going to pull my engine out and deal with some seals and such. ever since i got my engine running, i've wondered if my fuel pump timing is slightly retarded, because i consistently have smokey start ups w/ good plugs, 2 VERY strong batteries and a good starter. anyway, is the timing considered to be advanced when the mark on the pump is clockwise of the timing mark, or counterclockwise of it? any advantage to advancing the pump a bit? school me on effects of different changes in pump timing.
