I can't see any cracks, doesn't look like it has done much work. Set flywheel air gap sanded of flywheel. Got it started with electric drill, mowed front lawn.Changed oil put oil treatment in..... Put a starter on , and made a fine spring for carb....gotta fidle with that a bit. Finished mowing the yard. Nice little mower, easy start... no catcher but who needs one of those...... cheers speedy
