Hi Scott. Are you looking for Curtis or would you like me to help you with this? It sounds like you have a timing issue. You will need to put a timing light on this and verify the engine is in time. Let me know

Expert:  Dan replied 1 year ago.

Run-on by dieseling is caused by fuel in engine igniting without spark.
