This engine is on a 48" Craftsman GT5000 garden tractor. While mowing, it will lower the RPMs and lose a little power for about 5 seconds, then ramp right back up to full throttle. The mower still cuts and drives when it does this, but it is a nuisance. It does it about every 5 minutes or so while mowing, and it does not matter if it is going up a slope, down a slope, or on level terrain. The engine has been completely serviced, new spark plugs, oil, oil filter, air filter, and fuel filter. It also had an accelerator pump gasket/diaphragm replaced in the carburetor, and at that time the carb was completely cleaned. Any help would be greatly appreciated. Thanks.
