No eye bleach needed. There's a surprising number of those old "hundreds" still out there cutting grass. One-Lung Kawi's (Especially the FC540) still giving a shout-out to the whole neighborhood once a week or so. Muffler baffles have been gone since '94.
Biggest issue I've heard with them is the cam gear is plastic and will waste the motor when it goes, and you know the saying, if I heard it on the internet it must be true. I've actually have an extra motor that came with my first 185 that was the original for the tractor. Was replaced shortly before I purchased/stole it and could always open it up.
