I pulled a JS20 out of the scrap bin at the dump today. I got it home and without touching it had it running. Someone threw a running mower out. The self propelled part didn't work but it ran. I pulled the cover and adjusted the spring on the self propelled belt adjuster and like magic it worked. I cleaned the nearly clogged air filter and it started even easier.
Later this afternoon I fired it up and ran it a bit, then my wife took over. As she was mowing I noticed sparks coming out of the muffler. When she cut it off smoke was coming up from the top center, under the engine cover. The engine is a 6.75hp Briggs. WTF is wrong with it? Stuck exhaust valve? It mows clean and pulls hard. Aside from the sparks and smoke it's perfect. 🤣
