Why Cub Cadet Lawn Mower engine idles rough?
- WwmaynardAug 2, 2025
A rough idling engine in your Cub Cadet Lawn Mower could stem from several causes. The spark plug(s) might be fouled, faulty, or have a gap that's too wide, needing replacement and gap adjustment. Another potential cause is a dirty air cleaner, which means you should replace the air cleaner element and/or clean the pre-cleaner.
