Decarbonising
The decarbonising of the combustion chambers of a car or truck engine is a matter that sooner or later, requires the attention of every owner of an automobile.
Experienced motorists know the usual signs that indicate that it is time to decarbonise, such as a tendency for the engine to knock when running slowly on full throttle, and a tendency to roughness and loss of power. Many motorists who are the proud owners of their first car, are likely to be in doubt as to when they should have the engine decarbonised. Some car manufacturers recommend that the first freeing of carbon from the combustion chambers should be carried out after about 3,000 miles have been covered, so that the inlet and exhaust valves can be ground in.
This attention ensures that the valves are seating properly, that the effect of any slight warping of the cylinder block is counteracted and that the engine develops its full power.-—“Dunlop Bulletin.”
