To begin, this site is a godsend. Now, I bought this '70 Evinrude 40hp a few days ago and after starting I determined the bottom cylinder had a weak, intermittent spark. So I took the points off, (they were junk), and tried the ones off my parts motor. Wishful thinking. I went and bought new points and a fuel pump kit. Gapped my points .20, rebuilt pump, replaced fuel lines, checked spark plugs, and did a general clean-up. The end result is that now I cant get it to run at all, (sputters, floods, and backfires). So I changed carbs with the same result. Then I pulled the coil from the cylinder that keeps fouling the plug, and it tests fine (1.1 on lo ohms, and no reading from either lead when grounded against coil field). I guess I'm at the point when I would benefit from some greater knowledge, so if anyone cares to take a shot? Oh, I havent cleaned the new point contacts yet, I just read on this site that ANYTHING on them could make a difference, so I'll go do that while I wait and hope someone can help me.
