1968 fastwin 18 no spark

I just bought a boat with a fastwin 18 on it that won't start, there is no spark to either plug, the kill switch has been bypassed and the 2 wires connected together, I know nothing about these motors, any help would be greatly appreciated.

:shock:

I did that, the wires run to the points, 1 to each, I tested the coils per the videos on you tube, tested good, the points test good as do the plug wires.

How did you test coils? I got new ones & the secondary resistance was much lower than the new ones - I'm guessing the windings insulation had broken down.

I mostly tested for continuity, I had no spark at all so a weak spark was not my issue. Update to my problem : I took it all apart and cleaned all of the parts, put it back together, properly gapped the points and the coils, I now have fire, I checked the spark plugs again and found the gap to be completely closed, upon further inspection I found the pistons were making contact, the previous owner put the wrong plugs in it. I will put new in tomorrow, maybe the old girl will start. Wish me luck.

Put the new plugs in, it fired once and then no fire again, getting frustrated with it.
