I have a 2003 60" Lazer Z with a 23 hp Kohler Command w/ horizontal crank. Two days ago, it finally broke the worn out mule belt to the blades. I had another slightly worn belt that I put on, but the mower kept throwing it. I'll also add that it seemed like the full throttle RPM's had dropped at this point with or without the blades on. It was the last yard of the day, so we just trimmed out the rest of it. The next two days were completely full, and I didn't have a chance to look at the mower again. Just been using the 48" we have. Today, I got a new belt, and tightened up the mule pulley system. Put everything back together, and now the engine barely wants to crank. It turns over here and there, but it stops randomly. The starter is still trying, but the motor won't turn over. It has always done this a lot when the motor is cold. I attributed it to the old battery. I bought a new one, and finally got the motor to run. However, it ran HORRIBLY. Almost sounded like only one cylinder was firing. I changed the spark plugs Monday morning with Autolite 3924 gapped correctly. No problem Monday.
Anyway, I turned it back off, and it started the turn over 2 to 3 times thing and then stopping. I kept trying, but the starter started smoking a bit.
Any ideas where to start? A short block was put on about 2-3 years ago. Mower has 3200 hours.
I did try taking the spark plugs out to maybe shoot some carbon out if there was any. It turned over just fine with the spark plugs out. Shot a little cloud out on the first turn, but smooth and clean after that.
Thanks so much for the help. I don't want to waste time just trying things, so I came here to ask you all.
