Engine Craftsman 625 series engine seized

I have a craftsman 625 series push mower with a 190 cc briggs and stratton mower. My son was trying to mulch leaves last fall and the engine died and i initially couldn't get the engine to turn over. Eventually i got the engine to turn by getting the blade to turn by hand. I let the engine cool down and the engine would crank by pulling the pull start but the engine wouldn't start.

This spring i took off the head and i can see that the piston and valves look ok and rise and fall as i turn the blade by hand. The cylinder wall and valves don't appear damaged. I have purchased a new head gasket for it. The serial number above the muffler is 22 T02 08045-E1 and there is a number on the back 0610065918676. Does anyone know the head bolt torque values and sequence and any other ideas about this engine.



Thanks,



Dave
