Hi, Old Magnet.
Thank you, Sir. It's good to know that my past teachers were not BS-ing me.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

very interesting i know My Euclid is also positive ground. with them i think it had to do with the application. as them D.D motors where made like Lego with more than one mounting place so as to get the right rotation of the starter. if it dose have different gearing that could be why it seemed to have more H.P. i think OIH had a D2 with different gearing too i can't remember if it was faster or slower.

Faster gearing. I have a number of old machines that are of positive ground. It was quite common on the mish mash of old logging machines.
