Not sure but a picture might help............might as well try and fix it , nothing to lose 
engine case argggg!!!!!!!!!!!!!!
10 HP Briggs, while trying to pry off the flywheel, I punctured a hole in the top of the case. (I did try to use the pulley first but it still wouldn't budge so I used a large screw driver to help, bad move). Anyway their is a small square hole, around 1 inch by 1/2 inch. Can a patch be welded over the whole or can you patch it with JB weld? Any other ideas?
Thanks

If larger holes in the side of the block can be patched when the connecting rods let go I am sure a small hole in the top can be patched.
I patched a 10 hp BS block holed by a parted rod with linen cloth (bed sheet) & contact/rubber cement. The patch held my brothers until they moved up to dirt bikes (2 + yrs.). Might want to take some pains with the crankcase breather.

The consensus is to remove the engine, Pull the engine apart, LOCATE THE BROKEN PIECE!, and JB Weld it back in place.

An acquaintance of mine patched a hole in the block of a 4010 JD tractor with a regular fiberglass repair kit, and it held for as long as he owned the tractor.
Job completed. I tipped the engine over and was able to power rinse the inside of the case with cleaning solvent and a little 12 volt pump that I rigged up. There were two broken pieces that washed right on out. I then cleaned the outside of the case, patched the hole with JB Weld and a piece of aluminum. I also drilled and screwed the patch on as well. She fired right up and ran great. Hooray.
Thank you all for you advice.
