Potential causes Dieseling can occur for several reasons: Built-up carbon in the ignition chamber can glow red after the engine is off, providing a mechanism for igniting unburnt fuel. Such a thing can happen when the engine runs very rich, depositing unspent fuel and particles on the pistons and valves.

Can too much timing cause dieseling?
The fuel/airfuel/airThe stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.https://en.wikipedia.org › wikiAir–fuel ratio - Wikipedia mixture could be heated to the point that it self-ignites, causing the diesel run-on effect. 4) Timing is out. The timing itself won't cause the run on as the ignition is switched off when the run in occurs. However timing too far advanced can cause an overheating engine which can attribute to over-run.

What causes dieseling in a fuel injected engine?
Fuel injected engines will not diesel. The gasoline is ignited inside the engine by residual heat, either on the spark plug itself or from a hot spot on the cylinder walls or cylinder head. Dieseling is often caused by the idle speed of the engine being set too high.
Update On Engine Dieseling
Can old spark plugs cause dieseling?
Carbonized spark plugs can lead to engine overheating and dieseling.
Why does my engine try to keep running after turned off?
Running-on is when the engine continues to turn after you've switched off the ignition because the fuel /air mixture is being ignited by a hot-spot in the combustion chamber .
What happens with too much ignition timing?
If the spark timing is initiated too early, the cylinder may experience detonation and potentially cause damage. If the spark occurs too late, the engine runs flat, makes less power, and may overheat.
This Is A "Dieseling" Engine. It Defeated Me! 🥴
How do you cure an engine run-on?
Run the wire from the valve to an ignition-controlled live feed. Connect it in. Ask a friend to turn on the ignition, and listen to the valve —you should hear a distinct click as the ignition is turned on. Start the engine and check that it runs well and that the running-on is now cured.

How do you stop an engine from dieseling?
If it's an automatic - turn off the engine in drive. The added load usually stops it. Higher octane fuel will help. Higher octane fuel and a slower idle.
