So I haven't had time to get back to my engine since I was on vaca the past week, but looking at the JFP link the 2 drive "sprockets" in the illustration look very different. One company had them listed as "sprocket style" and "paddle style" when I was purchasing the used crank. Will the updated style even fit a dual row chain on it?
Here are photos of the 2 cranks I have (sorry they are just photos I took documenting the teardown/rebuild):
original setup - dual chain sprocket on right side of crank
Here is the replacement crank - sprockets on left - look the same with 2 sprockets rather than the almost timing belt pulley look of the tooth type chain in the pelican link
