What to do if my Kubota ZG127E-AU exhaust fumes are black?

If the exhaust fumes from your Kubota Lawn Mower are black, dark, or gray, it could be due to several reasons. You might be overloading the mower (reduce the load), using low-grade fuel (use specified fuel), have a clogged fuel filter (replace the fuel filter), a clogged air cleaner (clean or replace the air cleaner element), or the choke is not fully opened (check the choke position).
