the block is cracked and a friend says it can definately be welded but there is no inspection port to remove the connecting rod from the crank. It's a vertical shaft engine for a Murray lawn tractor. Also it is the L-head style.
Most will have either one side of block that comes off, or the bottom of block will come off.
Look for bolts that hold a plate of some sorts on the block.
I believe it will be on the flywheel side of the engine block.
Just read rest of question lol. With a vertical shaft engine you may find that the block is in two parts bolted togeather.
