I think I recall discussing whether I’d benefit from running a choke cable to my carburetor in a thread from some months ago. I decided that there’s no point to it as I am running rich at start-up as it is. There is no choke control on my carb at this ti, if I recall correctly.
Fortunately , the block off plate was included with my free manifold. Interesting how that hot air channel is incorporated into the underside of the manifold. It is a rather complex casting.
