Hi Ethan

I've had a look to understand the confusion, the grub screws that you are thinking of are only used on the 2 agricultural engines (the 2" and the 4"), and not any of our other models. This was because at one time the agricultural engines flywheels were a slack fit on the crankshaft, and needed them to help prevent the flywheel from moving. However all the flywheels are now a tight fit on the crankshaft, and therefore the flywheel key should be more than sufficient to prevent any movement.

Thanks
