I've been putting up with the surging and erratic running of this mower for quite some time. I ordered, but have not yet received, the larger pilot jet and different throttle plate to help cure the lean condition these motors were blessed with. While mowing on a steep bank I noticed the motor actually starving for fuel until I gave it a shot with the primer bulb. Finally, I pulled the carb completely off, and found two things drastically wrong. First, the filter box was assembled wrong in relationship to the choke shaft, causing the choke to work intermittently, and second, the carb bowl seemed to have more water than fuel in it, which would starve the main jet some of the time.

After proper assembly, it ran flawlessly, something I had never experienced with this Dura Force in the two years I've had it. I suspect that it had been run with ethanol in the fuel which carries a lot of moisture and accumulates in the carb bowl.

Hoping this might help someone with the same problem!
