Hi All,
My 2003 10323 had a surging problem since picking it up off Craiglist about a year ago. Cleaning the carb and setting the float height made no improvement. I took the carb off a scrap 10323 and drilled the pilot jet using a 77 drill (.018") and main jet with a 67 drill (.032"). The drill was chucked in a pin vin and simply used as a reamer for the process. What a difference, it runs without surging. As a advocate not to do this, I'm forced to eat my words. Strange part is my 99 10323 never had a surging problem, I wonder if Lawn-Boy used smaller jets in the later model Duraforce engines trying to get the engine to pass tighter and tighter emissions?
