I have a 70hp Chrysler 707HP that won't run. I did a complete service on the thing and had it running better than new, we're talking just bump the starter and 'vrooom'. I took it out and had a little fuel problem, and now it won't fire. I've got fire to the distributor, cleaned the points, and even have fire going to the "Magna-power" power pack via the blue ignition wire. Yet nothing to the plugs.(I tested this with an in-line spark tester) Like I said, it was running great and then, all of a sudden, nothing. It still turns, but won't fire. Any ideas???
