As I said earlier, cut the blade carrier off as close to the boss as you can,about half an inch away from the boss and if you are going to use a 3 jaw puller then cut the blade carrier in a triangle shape so you can get the jaws to grab onto the edge of the remaining boss. Honda uses a longish boss that is up fairly close to the underside of the motor so getting a 3 jaw to grab up there may be a problem. I find a bearing puller is the best way to remove these. At least if you cut the blade carrier off, then you can remove the motor from the frame and then it is much easier to work on the motor to remove the boss
