Have just partially rebuilt a Kohler KT17, using new battery, coil, leads, condenser and plugs. Checked voltage is getting to coil from RUN position, and continuity to earth all okay. Points are opening and closing, .020" gap. I have a new set of points, but the old ones looked fine, not burnt at all. Absolutely zero spark, so I am assuming something simple. The only thing of note is that somehow the battery was connected in reverse, obviously rectified, bht could this have wiped out condenser ?
