At this point, everything should be disconnected and clear to remove. Pull it out through the seat opening. It's not that heavy, your wife's purse probably weighs more
Now I pull the clutch, cover the carb and exhaust port with some plastic bags and hit it with the pressure washer. Makes less mess dropping caked dirt and nastiness on the bench. (And by the looks of my bench, clearly I frequently skip this step).
More to come. I'll start taking the motor apart tonight and measuring tolerances. I suspect we will find a broken piston ring but we will have to wait to find out :) much more to come
