Why does my Sole Diesel SM-82 Engine produce black smoke?
- SSharon LoweAug 25, 2025
Your Sole Diesel Engine may be producing black smoke due to: * A clogged fuel filter. Replace the fuel filter. * Dirty or faulty fuel injectors. Clean, test, and/or replace the fuel injector that is not operating properly. * An incorrect injection pump setting. Contact an Official Solé Diesel Service. * A clogged air filter. Replace the air filter element.
