For this reason, my first question was, what numbers have your engine stamped!!!Lars wrote:Aah, this is really interesting, Claudio.
Like a detective story, this is finally starting to make sense.
The Argentine Rumi Sport has the foot brake pedal support attached to the frame! Those unused lower mounting ears of the engine would interfere with that part of the frame. They would HAVE TO be cut, otherwise the engine would not fit in this frame.
At least, that is the way it looks form your photos. Do you agree?
If so, it would explain why so many engines with Argentine numbers have this modification!
