I have a John Deere L118 lawn tractor.
It was running fine, then it stalled. When I restarted, it was running extremely rough, not enough power to mow, and only to drive very slowly. It had previously been blowing black smoke, (especially when I put it in reverse and pushed the button to keep the PTO on)
It would barely run on full throttle, and when I pushed the choke forward it stalled.
I immediately replaced the spark plugs. (the old ones were black)
and I removed the air filter to examine. It seemed clean.
Same symptoms.
I took the spark plugs out and examined them. The left one was BLACK, and it was just replaced a few minutes ago !!
I sprayed small engine cleaner into the cylinders, and turned it over with the Left spark plug removed.
IT STARTED, and ran exactly the same, which leads me to believe that the left cylinder is NOT functioning.
is it NOT getting air?
I also noticed that the fuel filter only has a bit of fuel in it. Should it be full at all times?

Sounds to be a stuck Carburetor Float or Needle valve.

Smile John Deere L118

Hoping someone can give me some direction as to how to fix the drive belt (traction/engine) on my JD l118.
I removed the broken belt from the front and back end of the mower, however, I am not able to remove the entire belt as it is being blocked by the drive shaft/pinion.
Anyone know how to get the belt out without having to do a major overhaul or any tips on how to do this type of repair/replacement?

Thank you in advance.
