Is their still gas in the carb? Why is this happening? It does it once in a while but not all the time. Just curious. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | First guess is the timing is off causing the engine to "disel". I'd check it first thing. If that doesn't work let us know and we'll give you reason # 2-25....welcome to the bolt.

Dieseling is usually caused by a hot spot in one or more cylinders, often a glowing bit a carbon. Here is a short, simple explanation.

Thanks for the info. Interesting | | | | | Joined: Oct 2001 Posts: 3,458 Extreme Gabster | | Extreme Gabster Joined: Oct 2001 Posts: 3,458 | You may find that it goes away by either:
Replacing the spark plugs
Richening up the idle mixture
Rebuilding the carburator
Adjusting the valves
Running some "Seafoam" or Chem-tool through the tank
Using a plant mister to squirt a small amount of water into the intake when the engine is idling (but not enough to stall the engine)

Another quality post.
