B&S 450 (carburetor 285286) starts but dies after a while. I changed the gasoline to fresh, changed the spark plug and the air filter. I cleaned the carburetor. Everything is the same. If you spray carburetor cleaner into the air intake, it works fine, but without it, it dies after a while. What i shoul do more? Thanks in advance.

If it runs for a period and then dies and I don't mean a couple seconds of running and dying. More like 20+ seconds I would suspect a fuel flow restriction into the carb/fuel bowl. Basically fuel in doesn't equal fuel out.
