Update: Got the boss off.. took severl hard wacks.. few dents in the boss.. dont think its serious.. but.. seems I made a slight bend in the end of the crank shaft (where the blade-plate + nut screw onto .. I'd like to think that a minor bend is ok.. but spinning in circle at high rpm would likely cause a bad wobble/vibration
One of the shaft bearings was seized/rusted ,,, the other spins but may as-well replace both...
Which brings me to the last Question.. how the flip do I get the other half of the enging-case separated from the crank shaft
I;v tried bashing the end with the back-side of the hammer handle (wood), but just damages the handle
