I was mowing when suddenly my mower sounded like it was only running on one cylinder..my dixie has the 25hp kohler motor.. It will start and run but sounds funny and when i try to move it will bog down like it doesnt have enough power.. I checked and I have spark out of both plugs. I also put my finger on the spark plug hole and it seems to have great compression in both cylinders. I removed the plugs and one is clean and the other is a little black.. any suggestions would be great..
