I just rotated it 2-3 times with the breaker bar. It depends on how you classify easy vs. hard. I'd say it wasn't easy, but it wasn't hard. Some effort had to be made, but not all. I didn't notice any high spots.
All of the plugs were black. I'm going to order new ones. I don't have an AFR gauge, but I do know that my engine was running rich due to a manual choke cable I had not opening the carb completely for a year. I removed that almost a month ago.
Any recommendations on starters or water pumps? I noticed starter prices are all over the place $72 from a no-name on Amazon, $110~ for parts store, and $200+ for "high performance" ones on Summit.
