Been looking at this forum for days reading up on this little engine.

I do have a some questions that i just cant find the answer.. I did find some posts but all the links were bad.

1: Fuel pump diagram? I order a rebuilt kit and iboats didn't provide a diagram with the kit.

2: Spark.... I have pulled the flywheel and set the points and made sure that the were no loose wires and cleaned all contact points. I also have a new coils for both plugs but i still cant get good spark to one. I have tried to switching the condenser and still no spark. I ordered new points so i am waiting on them. Any ideas on what this could be? BTW the other spark is very strong especially after cleaning the points.

I did see a web page back in the day that was very help full. If someone were to direct me i would be great full... He had a hole page with pictures and diagrams.

if you use the coil kit that you have to assembly the boot, sometime they do not make contact, strip back some insulation, and wrap the wire directly around the spring contact. also if the pin in the coil did not hit the center core, can cause this symptom.

iboats doesn't even list a fuel pump kit for a 1975 15hp.http://www.iboats.com/Johnson_Fuel_...6652634--**********.308328548--view_id.271382

The best fuel pump information is from LeeRoy Wisner on his website. The top of the first page has the numbers for the kits. Copy the link to your browser without the quotation marks.
