Wow! Looking at that "before" picture, you've done an incredible job.
I don't want to sound argumentative about that airbox; I'm just trying to be helpful. Your engine looks like my Laura M48 with a water jacket added and, even though it looks like your carb is a Bing instead of my Encarwe, the configuration is the same. How much do you trust that the previous owner had it on correctly? Maybe somebody else who has an Odyssey can chime in?
I'm still curious about those fittings on the cables. Oilers?
