It looks like the old fuel gummed up the carb. I got some stabilizer from the mechanic when I picked up the mower. Hopefully that will prevent this from happening all the time.Could be.
I always use fuel stabilizer. Why? I forget how old my fuel is. Don't have to worry about old fuel anymore. My fuel doesn't get gummed up.
It’s hard to kill a 5 horsepower flathead Briggs engine, and it’s hard to kill a Briggs opposed twin.Use 100% gas.
If I could buy another antique B&S Flathead 22" Pusher, I would. Mine is 18 years old & still cutting like a hot knife thru butter. 1 pull starts.
They don't make em like they used to. (no offense me)..
