You’re right – it is in nice shape. Cowling dents/damage can make cowling removal so hard with this style of motor. I don’t know what the tempurature should be. A tempurate reader thingymajic is on my “maybe someday I’ll get one” list of tools.
Also, my understanding is that TC-W3 isn’t designed for the heat air-cooled engines generate because water cooled engines run colder, and it’s for the latter. I’d bet it’s less about running smoothly and more about lubrication and heat dissipation. Plus, it’s easy to find in real small bottles so you don’t have to buy a whole lot to just run the engine for a little while. 👍
