Hm. I have the 26" Craftsman which is almost the same thing as this, with the 208cc engine. Did I replace the carb? Yes. Have I really had to replace anything else? No. So many people recommending single stages. No thanks. 3 years old, ours has no rust, cables are all fine, belts are still fine, the paddles on the impeller are fine, still on the original shear pins. They aren't the highest quality machines at all, but they aren't the worst either
For $300, go for it, that's a good deal. When you finally do have to replace the carb, just pick up a genuine Honda carb, which is pretty much a direct fit.
Also, these 179cc engines are 5HP engines.
