I use carb cleaner and a penetrating oil together for rapid and deep penetration. Spray the carb cleaner in the cracks first and then spray the penetrate next. Give it a few minutes and then TAP the sides, both, of the key with a brass punch. Do not distort the key or you will truly have issues removing it. If needed you can apply a little heat to the shaft but not the coil plate. Good luck.
Hit a wall removing 420 PTO clutch
I was able to pull the engine out of my 420 tonight (thanks for everyone's advice on the previous belt tension issue). Now, I need to remove the PTO clutch/exhaust system, then intake manifold (in hopes of rebuilding the carb). I was able to remove the PTO armature, then the rotor. I now need to remove the key to get the remaining components of the clutch off so I can access the muffler bolt heads. The key seems pretty stuck in there. Reading other threads, it looks like the first step will be to pick up some penetrating oil tomorrow and get that working. Any other thoughts on tackling this?
