I have an Evinrude Mo# 9422S S/N E07020 9.5HP<br />Not sure of the year, but I inherited it and it has been sitting for a couple years. I have tried to start it and all looks good except that I pulled the plug and there is no spark. Plugs look good. Do I need to check the points and if so, How does the flywheel come off to get to them. Is it threaded on or keyed? Are there any tricks? I only want to get it working for sentimental value and the kids like a ride on the river... No one around my area will touch it.
