The thing is that the full crank engines are the older engines. From the early 50's to the 90's where the powertorque engine took over. The powertorque is not a full crank engine. So me personally I do prefer full crank engines. Mainly I guess the quality control was I lot higher back in those days. As far as advantages I'm not real sure as I don't have a lot to do with powertorque engines unless I'm fixing to sell or maintaining my mower. I prefer full cranks but I guess that's just due to that is the era that I'm collecting.
