I have a Wisconsin ABN that came with my Waterloo 40 walk behind. When I got it, it was in a box in pieces. It has been in the box for at least a decade according to the PO. It looks like the oil pump rod ceased & the oil stopped flowing so the connecting rod wore out at the crank (crank is okay). Anyway, I'm in the process of getting it back up and running.
Tonights question/concern was the condition of the cylinder. It looked bad & I thought I would need to have it bored, but how much oversize was unknown. I spent some time with a scotchbrite pad & then with my hone. It looks like I am still within spec, or within a thou either side. I still have some finish honing to do, but I am encouraged. Thought you all might like to see the results. I would have done more, but my hone threw the stones when I pulled it out of the cylinder. Considering this is my first time honing a cylinder, I am happy with the results.
