Why is my Kubota RTV520 Utility Vehicle engine running rough?
- JJay EdwardsAug 27, 2025
Rough engine running in your Kubota Utility Vehicle could be due to a defective spark plug, so adjust the spark plug gap or replace it. The fuel hose may be clogged or damaged, so clean or replace fuel lines. Also, improper or stale fuel may be the cause, so replace the fuel. Check if the air cleaner is clogged and clean or replace the air cleaner element.
