G'day MrMckay, They are known for their longevity. I haven't come across scored bores in these, no matter how dirty they are inside. The only one I scrapped had a broken ring, because it wasn't assembled right.
There are a lot of these in the USA used on commercial machines, hover mowers & snowblowers. Here is a thread in America discussing Suzuki or Toro 2 cycle engines.

Chris, thanks for the tips, I use this to seal the crankcase.

In the 2 manuals I have, one states:
5. Assure both halves of the crankcase are clean and free of grease and old sealant.
Apply a thin uniform amount of Threebond #1104 or Loctite #515 sealant to the mating surfaces and position the crankcase halves together.

The other manual: recommends Suzuki bond no.4.

Christo, love the filter. That one will need to pulled down and cleaned out.

The reason these engines fail is:
1. Air filter as above
2. Choked fins stopping cooling
3. No oil in the fuel

A lot get discarded because they have diry carbs and water in the tank.
I live in a rural area, and ones I get are not good, I'm sure somewhere on the mower is says please trash me.

Below is what I came up with for the snorkel.
