Sounds like my '66 Midget (RIP).   On hot days, I could not get above 3500
RPM.  It was the fuel vaporizing in the lines.  I insulated the line from
the manifold area and the problem went away.  Modern gasoline is more
troublesome in this regard than the stuff available back when the car was
built.
