Husqvarna YTH2348 with Briggs and Stratton 23HP engine model number 445577
There are several things that cause the mower to sputter, lose power, and blow white smoke: throttling up too quickly, turning the blades on at high throttle, throttling up too high when the blades are on. Any of these things will cause the motor to sputter, lose power, and blow white smoke. The rumbling sounds very much like a Harley. Once this starts, I have to throttle all the way down until the motor calms down. Then I'm able run it normally until it starts again.
I've taken the carb apart, cleaned it, and replaced the O-ring that was completely out of shape and flat. I truly thought the new O-ring would fix it, but it still does it. I've also changed the oil and put in fresh ethanol free gas.
I can only turn the blades on at the lowest throttle and haven't been able to cut grass yet.
