I have a sears yt4000 that is stalling/surging after about 10 minutes of mowing. It acts like it is starving for gas. I have read through many posting on this and have done the following, replaced fuel filter, fuel pump, cleaned gas cap, and checked valve settings and it still does it. Will keep running if I disengage the mower deck and throttle down. The governor keeps opening and closing the throttle and then will smooth out. It will then take full throttle and will run with the mower engaged for about two minutes and then do it again. The carb was replaced two years ago. All maintenance has been kept up. What else to check?
