It smokes a little, and uses a lot of gas, but it always works. It has been repainted lime green and renamed the "Swamp Rat." The muffler was also removed, because why not? Including spray paint, it has cost maybe $1 a year over the last 20 years to keep this mower in running, working condition. Not bad. I changed the oil once and topped it off since then. The old oil was pitch black, but the mower was running fine.
I was given a "non-running"'96 B&S Murray that had been left outside all winter. I just drained out the varnish and water mixture in the tank, refilled it with fresh gas and SeaFoam, put a new air filter to replace the dry rotted/turns to dust when you touch it filter, Replaced the original plug, Hosed the carb down with DeepCreep, changed the oil and started it up on about the second pull.
The muffler has a big hole in it and a long crack. I'm afraid to try to take it off because I'm pretty sure it will break off and just leave a small part inside the engine. So I just leave it alone.
