I have a 1965 40 hp (rds-27m) johnson. It has a copper tube running from the electric choke unit on the side of the carburetor, to a threaded port on the side of the exhaust cover....There is actually two threaded holes in the exhaust cover, one has nothing in it currently. My question(s) is, what is this tube for?? ….And can these two threaded ports just be plugged??…
I pulled up a few exploded parts diagrams of this motor, but they give no explanation as to what these ports and hose are for
.I intend on manually choking this motor, as I removed the wiring harness.
