    Thanks for the response. the problems where present prior to the tune up. have used the factory required parts for air, fuel and oil filters. Although the mower was purhcased in 2004, it only has 38 hours on it (Yes 38 actual hours) and the oil/filter have been changed 3 times. It was purhcased when I had a much larger yard to mow. Prior to this problem, the engine would automaticall power up when the blade was engaged and you could hear a difference in the power. Although the blades are spinning, there is a clear differnce in the RPM's from the engine

Check bearings on the mower, grease them if you can. Check the deck for packed in grass and gunk. Check where the deck gets the power from the engine, see if it needs grease or lube. Check jets on the carb if it has any, slowly turn it in (clockwise) until it is as fast as it goes, then back it off half a turn or so. If it doesn't get faster, turn it the other way til it gets to its peak, then back it off a little. Check the spark plug, it should be a light brown/light gray color. Make sure the gap is right on the plug also. Check the plug wire(s) for melted spots, if they are a few years old, probably just replace. Are you using fresh gas? The tank hasn't been the one from winter I hope. Make sure it is not mixed if it is not supposed to be. May have a blue tint if it is mixed. Check ground wires, and battery cables for tightness and corrosion. Hope this helps.

    If it is supposed to rev up a little when the deck is engaged, it may need the carb to be cleaned/adjusted.

Might pull the plug and check for spark with that plug, possibly just fouled it out. If the engine spins maybe faster than normal, or an occasional pop or backfire, the flywheel key may have sheared.
is the radiator clear and free of debris.
If the problems going uphill began after your tune-up then it is most likely related to the fuel filter or air filter you used. If the tractor is not running badly or hot at any other times, the issue is not likely to be related to the spark plug you used.There are a couple different engines that might be in aYH2148, but some are pretty sensitive to any added restrictions from an incorrect air or fuel filter, so a universal or incorrect filter could be limiting overall horsepower which is showing up under the added load on hills.
You might want to try installing the recommended filters for your exact model to see if that improves matters. You can find the parts recommended for your particular model at theSears PartsDirect website.
If the problem was already present before your tune-up, then you might have an issue with the drive belt or brakes, either due to wear or mis adjustment. Or you might have an issue with the throttle/governor settings or even an issue with excess engine wear.

make any carburetor adjustments AND CHECK OUT.

Hi. Begin by checking your blades, if they are dull they must be sharpened or that alone will bog down the engine. Also time for a new air filter. Happy mowing. J.

I have Briggs 18.5 horse and after I mow for a while the motor will bog down and quit unless I dis-engage the blades. I removed the spark plug and it looks wet. I replaced it and after a short time again...

If the engine runs ok when the blades are not
engaged then the engine is all right. Maybe its a faulty safety blade switch or a wire to the switch is stripped and is earthing to the body. Stephen
