Nothing wrong with the engine as far as I know. I just bought this tractor and had no history of past performance (non-running but at a good price, knowing that if it needed engine work I'd still be ok with it) so I tore it down to check the sump for extra parts floating around and the condition of the balance gears. While in there I noticed the rod clearance was excessive. Taking the crank out for a regrind I decided (why wouldn't you) to check and bore the cylinder. That's how I got to this point. The block is still a standard bore so I was planning on a .010" oversize when the machine shop questioned the clearance. His shop floor is full of blocks so I'm guessing he's been there before. Maybe he was just working on a small block and had other clearances in mind, not thinking of the air cooled issue as mentioned by J-Mech. I just as soon he question as to what he thinks is correct, at least it shows he's thinking. Initially, I brought the block in to get measured so I know what piston to order so he can have it in hand to hone the cylinder to.
