The carb bowl did not do any good after all. As per usual, it
started, I was able to mow for about 10 minutes, it sputtered for about
another minute and then shut down entirely. IT is a 139 cc PowerMore
engine on an MTD self-propelled mower. Only about 2.5 years old.



Air filter dirty?

Nah. One of the first things I looked at.

The MTD site gives 6 things to check for: Engine runs erratic

1 Spark plug wire loose -- Connect and tighten spark plug wire


2 Blocked fuel line or stale fuel -- Clean fuel line and fill tank
with fresh gas


3 Vent in gas cap is plugged -- Clear Vent


4 Water or dirt in fuel system -- Drain fuel tank and refill with
fresh fuel


5 Carburetor is out of adjustment -- Adjust carburetor according to
your engine manual


6 Engine is overfilled with oil -- Drain oil and fill to proper amount
