It looks as though there’s another project on the horizon. I couldn’t resist.
For those who are not familiar with it, the GS190 (mfg ~2008/09 to ~2018) is similar to the cheaper GC engine architecture, but was upgraded with a cast-iron cylinder liner, 3-piece oil control ring, and all-ball-bearing crankshaft, plus cast alloy valve cover. It retained the same nylon cam and toothed rubber timing belt, so this is strictly a run-as-stock engine. But it’s lighter, smoother, and quieter than a GX clone/Predator, and I really like that it has a vertical cylinder. It’s also somewhat unusual, which makes it a little more interesting.
This one is NOS from very early in production. The serial number is #1795, and it has the “6.0” on the decal, which they did away with fairly quickly, because it is actually a 5.2 HP engine by ANSI test methods.
