I have a 5 or so year old craftsman riding lawn mower 48 inch cut. It
seems to run fine while mowing if th eblades are engaged. However, when
I turn the blades off after mowing for awhile, the engine surges like
someone is making the throttle go up and down. It "jerks" while you are
tryign to drive it. I can remember if it still surges when in neutral
or not but it is bothersome when you have to drive somewhere with the
Any advice on what is the problem and how I address it?
