actually if you look at the physics of a flywheel you will find that diameter impacts torque more than weight but with that said weight still has impact . The ratio of the crank and piston weight of the John Deere d may in relationship to the flyweel weight of the d could be a identical ratio of the 11 pin sprockets mass to the 660 crank and piston mass .If the ratio same then both are impacted the same. Alot of internet experts on any forums including this one. Wither we agree something like the sprocket is impacting the clutchs frictional point of lockup or not once the clutch is fully locked the weight of the sprocket is part of the total rotational massRight, anyone who thinks a sprocket is going to make any difference on cranking doesn't have all of his marbles, plus he thinks the sprocket maybe 1/2# has a flywheel effect. Maybe if it was a flywheel off a D John Deere that weighs 300# it might have a flywheel effect. This boy has a lot to learn about physics . Steve
