Why is there excessive black smoke from my Toro RT1200 exhaust?
- MMichelle WilliamsSep 7, 2025
Excessive black smoke in the exhaust may be caused by dirty air cleaning system elements (service them) or improper fuel in the fuel system (drain and flush the fuel system, then add fresh fuel). For issues with the injection pump timing, a damaged injection pump or nozzles, or a damaged turbo charger, contact your Authorized Service Dealer.
