| | Re: Indexing Evinrude FICHT Plugs
Take the plugs that don't line up and try them on the other side. I would not chunck any of the plugs because the don't line up perfectly. The effect of not being indexed properly is that the plugs will not last as long.
I would suggest that you DECARB these engines without delay. Carbon causes these engines to die an premature and ugly death. The Seafoam method works well. On my engine spraying it in the air intakes did the job best, but you really need it in a test tank or in the water to give it some back pressure. These engines will want to over rev.
