My Craftsman 6.0 B&S motor start only if I prime it at the spark or by spraying
carb cleaner at the filter(discover this by accident whille cleaning the carb).
It still running fine and if stop it for a couple of minutes it start again, but not for long time off.
Any idea of what wrong...air leak...carb...or?

if its the primer carb the primer button may have holes, your not getting good spark. but if it ran good a couple mins ago, then everything should be fine... check spark right after running it, and clean the carburetro real good.

If the primer is in the air filter base, then you might need to replace the mounting gasket between the carburetor and the air filter base. If the seal is not any good then the primer will not work, but it will not affect the running once you get the engine started.
