I replaced the cog on the underside of the pull start mechanism. It's a gadget that engages the flywheel notch when you pull the rope. The new one seems to rub on the flywheel. I tried it right side up and upside down, right side up rubs less. Does it just need to "wear in" as I run it, or do I need to carry tools and a spare plastic cog when I go fishing?
