21/8/15From the photo of the Ottawa two cylinder engine, I would like to know if these engines used a 180 degree or a 360 degree crank. The engine has no distributor, so I would assume it to be a 360 degree crank. I can find no literature that shows this. As you might already know, Harley motorcycles worked this way, no distributor, just points. The Indian had a distributor just like a car. A collector near here has a Cat 60 with the fuel pump about the same place as on the Cat 70. This 60 has no vacuum tank, it also has levers for steering, not the usual cranks. Max R.

21/8/16 Q. I have been told that a number of 22-36 McCormick-Deering tractors were re-powered shortly after World War 2 with Detroit 4-71 diesel engines. The report says that new tractors were not yet available but diesel engines could be purchased, thus the conversions. Can any GEM readers verify this report or supply further details in this regard?

A. The Reflector has some hazy recollections of this practice, but we cannot recall with certainty whether it was the 22-36 which gained the transplanted Detroit or some other tractor model. Would anyone with details of this practice kindly contact the Reflector. We too would like to hear more about this.
