I noticed that both the fastrak and mini fastrak are available with a 16 hp honda twin engine. I am assuming that these engines are tuned differently as the fastrak specifications indicate a max. torque of 31.7 ft lbs @ 2500 rpm whereas the mini fastrak specifications show a max. torque of 26.9 ft lbs @ 2500 rpm. Is this correct that the fastrak 16 hp honda engine produces roughly 20% more torque than the mini fastrak 16 hp honda engine. It appears that the single cylinder Kohler engine on the mini fastrak 42 produces more torque (27.9 ft lbs) as well as more horsepower than the corresponding 16 hp honda engine. What is the advantage of the honda over the kohler engine in this application. I am trying to decide between these engines. Thanks!
