You guys helped me get an old Johnson running last winter, but I can't find the thread. This year, I have an issue with the pull start. It seems that there are little 'cogs' that grab the shaft and turn it when you pull the starter rope. The little cogs it appears are replaceable, as there are little pieces of metal that screw in to keep the cogs in place. I think there are 3 of them. It seems that the cogs are a softer type of metal, and were designed to be replaced. Guess my question is, any idea how I can get replacements. The motor has a badge that says 'Outboard Motor Corp'. Thanks.
