Why does my Lister Petter TX3 Engine have excessive carbon deposits?
- KKevin PerryAug 21, 2025
Excessive carbon deposits in your Lister Petter Engine can be caused by several factors. These include a choked air filter, a choked exhaust system, unsuitable fuel, unsuitable lubricating oil, or continuous low or no-load running. To resolve this, dismantle and clean the cap and element of the air filter if it is choked, dismantle and clean the exhaust system if it is choked, use fuel of the correct specification if the fuel is unsuitable, and use oil of the correct viscosity and specification if the lubricating oil is unsuitable. Also, investigate your load management program if the engine is continuously running at a low or no load.
