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?
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.
