Good day,
While chasing my warm starting issue, I removed the throttle body (throttle plate assembly?) from the intake manifold and noticed a tiny set screw near the back of the assembly.
Does anyone know for what this is used? It connects to a vacuum port in the body, but spraying cleaner into the hole didn’t reveal where it leads.
Btw, this car is a 1967 230sl with the M127 engine.
Thanks for your ideas!
