Measure the depth of the crank slot, then measure the depth of the flywheel slot. Add the depths together and the sum will give you a big clue as to the HEIGHT of the key correct size; there may be several "sizes" in that height dimension, e.g., longer or shorter on the "flat" side and a different radius on the "round" side. If this process is not clear, I will make some tutorial photos and further instructions. You can buy a few different sizes and give 'em a try. Review that McMaster-Carr link above and see if that describes the dimensions.
edit: I looked at McM-Carr --- also measure the WIDTH of your crank slot
