I looked at the 1 I have, after clearing the cob webs off, it's a gc160 model.
If I remember correctly, been awhile since I've worked on those OHC engines, the GS model has a steel sleeve for industrial/ commercial use, while the GC has the aluminum bore, for light duty work.
I would pay $20, if it started, but I have customers that's always looking for pump, compressor engines, and it would go to a new home....quickly.
