20B It still runs, but not good.  Thanks for all your suggestions.  New gas with exactly measured oil made no difference.

However, I put the timing light on each of the plug leads and was really confused at what I saw.
    #1, both lead and trail, 35 degrees before TDC  So good so far.
    #2,   "        "      "      "    mostly 35 degrees Btdc, and an ocasanal 120 off from that
    # 3                                 A lot of 240 degrees (about where it should be) and a lot at 35 Btdc.

After looking at that, I am surprised it runs at all.  And Tracy won't be back till next week.  I am hopeing  that the extra length of my embilical cord from the firewall to engine (Seawind) accounts for all of that, but I have a hard time convincing myself that is so.


Any other good ideas?????

You said there was a long run of wires.  Are the tied closely together?  Could you have crosstalk causing the extra firing?  Would it be difficult to "fluff" the bundle and try it again?
