Hi,
I am in the process of restoring a 72 Starcraft. It came with a 1979 140hp evinrude motor which I had planed on retiring. It looked pretty rough under the hood. I took it off the boat to replace the transom. The gentleman I purchased the boat from had rebuilt the carbs, but could not get spark. I decided to check the compression, and got all cylinders between 125 and 130. Now I'm thinking about putting it back on the boat if I can figure out the spark issue. It has new plugs. That is about the extent of my knowledge on the ignition system. I believe two of the coils are probably bad They are rusty. The other two coils look fairly new. I figure on replacing all four. None of the cylinders have spark. So my question is what is the next component to check or replace. My usual method is to start replacing cheapest to most expensive parts, but they are all pretty salty. So I was wondering if anyone more familiar with this motor might have any suggestions where to start.
Thanks, Dave
