    I have a 12.5 kohler command that is surging after you start it.When you engage the blades it quits.It has fresh gas and I have checked the air filter.I rebuilt the carburator and it still does it.What could I do to fix this.Thanks.

    Start the engine and throttle it up just a little until it starts to surge then apply the choke slowly and see it it smooths out. If so there is still something restricting the slow speed circuit in the carb. and needs more cleaning. Use carb. choke spray cleaner with the little tube in the nozzle to get into all ports.
